That is really weird. Well regardless of the intention, I do like the result, a spin off game that doesn't affect the main series and let's new talent make something different. I like this as much as I like seeing different interpretations of characters in comic spinoffs and the like.
If it works, awesome something familiar yet new to enjoy. If it doesn't, it doesn't affect the main series anyway so it's easily ignored.
See my issue is this doesn't retain much of Sonic from the looks of things and a lot of designs (The robots) just scream generic baddies. I'd also wonder that if Sonic Team themselves were behind this, would the character designs be getting a lot more criticism?
It's not like I'm new to facelifts either, Godzilla gets a new canon and appearance in almost every single film but the designs almost always retain what makes the series Godzilla. This though kind of reminds me of the 1998 American abomination.
I am excited about several things (The talent, the level design) but I am disappointed at the same time. The art direction seems bad, the co-op is something I never wanted in a Sonic game but above all else, if SEGA wanted to establish a new continuity with Sonic, why did they not just go with classic Sonic getting his own series?
I think the sales of Sonic's latest games are declining as Sonic Team don't seem to have any genuine ideas on how to create a 100% fun Sonic game. Generations game close for many, but it still had its problems.
Honestly it's more to do with Sonic being on a dead platform. The Wii U has seen every series premier exclusively on it shown massive declines whilst the 3DS is in a head on battle with the mobile space (Something Sonic is doing extremely well at mind). Once Sonic hits multi platform status again, you'll see the series hit back to 1.9 million+ debuts in first 6 months. It would help that by 2015 the Wii U should have a more sizeable userbase.
Sonic Team also has more leeway of making other IPs than the other teams, and given how most people know who NiGHTS is, Sonic Team can take a few risks now and again on a new Non-Sonic project.
NiGHTS might have a vocal fanbase but they are just that, in truth the majority of sales of the original NiGHTS came from Japan. Ristar and Burning Rangers were also commercial flops and Billy Hatcher barely managed to break past a million.
In truth for every 10 new IPs SEGA develops, only 1 or 2 are considered a success. Binary Domain, Vanquish, MadWorld, Anarchy Reigns, Stormrise, End of Eternity, The Club and Rise of Nightmares all flopped. Compare that with 7th Dragon, Bayonetta and Valkyria Chronicles... One of which was not really that successful. We can see from the titles that are coming out this year (Ryu Ga Gotoku: Ishin, Hero Bank, Project 575 and Alien: Isolation) SEGA still wants to take risks, but already one of those risky games have failed so...
Though do keep in mind SEGA's staff move around the
company.
