I would have to disagree I haven't encountered any problems with Modern Sonic in Forces at all, however Classic is somewhat heavy, although he's probably better off not returning for the sequel. Shadow is just a reskin of Modern Sonic much like he was in Adventure 2 & Heroes, so of course he has no problems. Then the Avatar that depends on your species, although most of them seem to handle the game rather well. Also the levels don't seem all that short, except for the Extra/Secret Stages. Overall most stages seem to be about the same length as Acts from Sonic 2 or Sonic Rush. Also Automated sections are in several Sonic Games.
