While this game is great for the nostalgia, the main game is over way too soon, which all the extra 'modes' just replaying the same game over again which different attributes of extra characters. I was very disappointed to not see the ability to play the original games (Sonic 1, 2, 3) or even a full iteration of the Mean Bean Machine. Being able to play through all the original games, not just this remake of a few chosen levels (No Marble Garden Zone?!?) would have added a lot of replayability and kept me playing for weeks, not for days. Great idea for a PS4 release, just not enough content.
