Honestly I think they could make a good 'modern' sonic game if they made something like unleashed/generations but WITHOUT the sidescrolling. For some reason they had entire dedicated sidescrolling levels in generations with 'classic sonic' and still decided to shove in some flow-obliterating sidescrolling platform segments in the 'modern sonic' levels.
(This is what I'm talking about, though there were definitely examples more extreme than this)I just want a game where I can go fast, dodge obstacles, and build combos without having to slow to a snail's pace and do some platforming puzzles.
