Yes and sadly in the Q3 Financial Results, Sonic Rumble has been noted as a major disappointment for SEGA. The company cited the mobile title for weak performance, specifically pointing to poor customer acquisition and lower-than-expected user engagement.
The game wasn't even in the Top 10 SEGA mobile games in term of revenue.
Here's a comparison for the last 30 days revenue compared to some other SEGA mobile games on iOS :

That sucks. One thing Mario has over Sonic is multiplayer engagement, such as sports, karts and party games. Sonic Rumble is one of Sonic's major multiplayer game and it's doing bad.
Okay, I will try to give my opinion on this but using a business perspective so it's gonna sound harsh.
1. SEGA has already have a toy division and they're rather making Disney, Miku, and Marvel toys rather than SEGA characters (with the exception of Sonic). Why? Because SEGA-based characters don't sell much compared to Disney, Miku, and Marvel. They got more profit in licensing them to other manufacturer instead.
2. SEGA has a mobile app now for UFO Catcher which worked quite well, so I'm sure they could make app for smart phones to be used as "toy pads" for their toys but of course what the use if the toys don't sell enough.
3. A game with camera and kinect is a niche market so I don't think they're touching it right now and use their resources to focus on the mainline games instead.
4. SEGA already had a party game. It still couldn't beat Mario Party and I'm sure it still couldn't beat it even the characters were changed into SEGA All Stars. It's just make looks like Mario alone could beat SEGA All Stars if there's such a game which dragging down SEGA name. SEGA is careful with their brand name now.
5. VR market is still a niche, otherwise EA, Microsoft, Nintendo, and Sony would make a lot of games for them.
6. Unfortunately Sonic Rumble and CrossWorlds didn't meet SEGA's expectation even though both games were full of SEGA classic characters.
7. I can see Shinobi Origins could happen if Shinobi AOV was asuccess but sadly that wasn't the case.
8. Still I think there is a hope for Sega All-Stars × Fighters Megamix if Virtua Fighter Crossroads became a success, but probably RGG Studio is too busy with another Yakuza games to make one (unless higher ups at SEGA stepped in and told them to).
As personal preference, I do want SEGA made VR Space Harrier or SEGA Olympic Games with SEGA characters in it but from business perspective I understand why SEGA wouldn't even consider it right now.
- Sega character toys don't sell because Sega aren't doing much or enough with the IPs for those toys. This is why Toy to Life figurines specifically so that these toys can have more value and uses. But if Sega sticks to "playing it safe" with Disney, Miku and Marvel, then they might as well grovel to Nintendo over a Sega All-Stars amiibo deal, or not bother at all.
- Or if they won't make toys for it at all. I'm reminded of Dinosaur King and MushiKing, while these arcade games did not leave Japan, they were still popular for having barcoded cards, so digital-interactive toys could still work.
- It is a niche market, I agree. I believe if Sega want to bring more attention to their classic IPs, a sequel to Sega Superstars is a way to go. On one hand, giving it a niche would likely strict it and be bad marketing, but the first Sega Superstars game was renown for being an EyeToy game, so a niche may work for it?
- Sonic Shuffle is both a Mario Party rip-off and poorly executed. I don't think I have what it takes to convince you or anyone it isn't as bad of a party board game as the whole fandom accepted as, for example, I thought the use of cards over dice-rolls was rather clever and original. It provides a layer of strategy that I don't think any Mario Party game has, where having the right number cards or risk taking an unknown card from an opponent may make or break a turn. Other than that, Sonic Shuffle was made 26 years a go and Mario Party has comes such a long way that if Sega were to decide to release a "Sonic Shuffle 2", whenever a direct sequel or part of Sega All-Stars, it would be vastly different from both the first game and current Mario Party games at this point. I mean, would you say "Sonic Racing: Crossworld" is a "rip-off" of Mario Kart World? After all, Sonic Racing is a cartoon-like racing game with pick-ups to throw at one another etc.
- VALVe and Sony made a few. But that's why I would like to see a "Sega Superstars VR" game so that it would be less of a niche. But I understand that it would still be too much of a niche for Sega to make a game over.
- But both games still have active market, Sega hasn't seem to pull the plug on them yet.
- There is still upcoming Streets of Rage, Golden Axe, Jet Set Radio and Crazy Taxi games.
- That's why get Sega AM2 do make it. They can reuse VF5 engine to make it.
Well, it seems to be that Sega pretty much shot their classic IPs in the foot at this point. If they want to renew audience interest in their classic IPs, then the Sega All-Star franchise would be the best way to do it. But it doesn't seem they are willing to take risks to make it happen.
When the "Sega Renaissance" started, they have given permission to various developers and producers to make their games because they didn't want to take the risk of making games with poor expectations. But when Lizardcube made a baller with Streets of Rage 4, they hired Lizardcube to make Shinobi: AoV, and now they are disappointed that the game hasn't met "their" expectations.
But it's not like Lizardcube are at fault here. They didn't make a bad game, it's just there are other ninja games on the market, and Shinobi hasn't had a fresh game before AoV in years. And why? Because Sega didn't want to risk it. But in not taking risk, there is no reward!
This is something I praised "Classic-era Sega" with. They took risks and, while not always, were rewarded with it.
Sega employee: "Sir, we released the Mega Drive to compete with the NES, but there is a problem... Nintendo will release the SNES in three years time, and it will have better specs than the Mega Drive. What should we do?"
Sega boss: "We effin' take 'em on! We're still a decent console. Is there anything the Mega Drive exceed at over the SNES?"
Sega employee: "Well, we have faster processing power to them, but everything else is just-"
Sega boss: "We'll call it BLAST PROCESSING!"
Sega of now:
Sega employee: "Sonic Racing Crossworld is very popular, fans even say it's better than Mario Kart World."
Sega boss: "But is it making as much money as Mario Kart World?"
Sega employee: "Well no, but only because Mario Kart World is $80 along with the $500 console exclusive on, but there are still lots of-"
Sega boss: "Crossworld has failed my expectations."
Sega employee: "We're still giving it a three year DLC marketing though."
In fact, I will predict that none of the "Power Surge" games will meet expectations for Sega. Not to say I'm predicting they will be terrible, just it seems Sega's standards are a bit too high strung.
Sega, if you're "playing it safe" and you're
still disappointed in your sale numbers, then perhaps what you're currently doing is just not efficient enough any more. That and I feel you're not getting full feedback from the fans. Shinobi: AoV wasn't a great game, but it was still good for a Shinobi game. And if you made a "Shinobi Origins" then perhaps people would have more appreciation of the IP.
That's all I can think to recommend for Sega. More "Origin" games and more Sega All-Star games. But if they're not going to risk it like their predecessors, then might as well continue sitting on those IPs and doing nothing with them.
