Sega admits Sonic is falling

[Goemar]

Wow that was dumb.

Making something 3D isn't bad. Sometimes games REALLY shouldn't be made 3D (Metal Slug) but company's want quick cash and thus make a cheap 3D pile of crap. But if, somehow, a good 3D Metal Slug game was made I wouldn't dislike it just because it was 3D as long as it was a good Metal Slug game.
And that's another point, when making a game 3D the spirit of the game shouldn't be lost. It should still feel like it's part of the series.

Sonic in my eyes is suffering from this. The newer Sonic games sometimes slip into the "this isn't Sonic" territory hurting the game quite badly, aka turning into a wolf, swinging a sword, working with knuckles etc. If your going to change what makes a Sonic game, a Sonic game - why not make it a non-Sonic game?

The 3D Mario games feel like Mario games. Even though I thought Sunshine was rather bad it still felt like a Mario game. Most of the new Sonic games are not only bog-standard platform games (often worse then the later Crash Bandicoot games) but often fail to capture that sense of "this is a Sonic game."
