Sonic Lost World is out. It has received a mixed reception. Scoring 5/10's from some reviewers, and 9/10's from others. The Wii U version holds a Metacritic score of 63, wheras the 3DS version holds a Metacritic score of 61.
What would you like to see for the next Sonic game? I would personally like to see the parkour gameplay return, but sped up, and for "grounded" regular level design to return, more creative level tropes, and tougher bosses. I think the parkour gameplay has a lot of potential. I would also like to see other characters playable, but that might be pushing it as SEGA seems to just want Sonic as the only playable character right now.
