Thanks for the suggestions! Stuff from former developers that continue the legacy of IPs I totally think belong, like Ed's project, but I'm iffy on including games from devs who are simply fans.
I agree, I think SEGA's Legacy should be limited on "connected to the SEGA's IPs (or used to be their IPs)", not "inspired by SEGA's IPs", or "made by the guy who used to be in SEGA", because I believe there are so many of them, especially for mobile.
One of them is Dashy Crashy, made by Travis Ryan (Outrun 2, Sega All-Stars Racing). Personally I love the game, and I'm hype for Drift Stage and Slipstream too, but still I don't think they are connected to SEGA's Legacy.
But with my description, it will means Yuji Naka's Rodea The Sky Soldier would not be included too, so I open to another description about what SEGA's Legacy is. I'm waiting for other's opinion.
About Ed's project expected to be reintroduced soon, is there any link of it?
I tried googling it but couldn't find any. The closest I got is Sound Wave
, a tribute album for Ecco.
