It has nothing to do with nostalgia.. Sonic is simply much better in 2D! #DealWithIt

So then we would still be ignoring nintendo and playing with a computer instead of a console. Big deal.

Sonic can work as a 3D game, but after Sonic Adventure 2, Sonic team wasn't focused on the right thing IMO. Look at series like Super Mario 64, Bomberman 64, or even Kirby Crystal Shards, excellent games that kept there core and succesfully translated into 3D.

Sonic Adventure was a good foray into 3D but got distracted with the Adventure aspect of it. Sonic Adventure 2 streamlined it to make it more of an Sonic game but the exploration and Mecha modes, although adding some variety, were alien from the core of Sonic which is speed platforming as opposed to Mario which is Exploration Platforming.

The speed sections in Sonic Adventure 2 were better than in Sonic Adventure 1, but the platforming and speed sections were too divorced possibly due to the limitations of the hardware. With Heroes, they streamlined it even more, but practically every full 3D sonic hasn't fully focused on the speed aspect which is the core of what Sonic is. SA and SA2 were the closest. STH and S06 got distracted too much by story, which is unnecessary because Sonic games story has never been crucial, and S06 made it even worse by bring the Adventure aspect of SA back in full force.

The 2.5 D Sonics excel because they are getting back to the roots of Sonic, that is a speed platformer. Generations, was basically Sonic Unleashed minus Werehog and that worked excellently, but that only because they were working within the same formula from Sonic's of old.

If Sonic as a medium is going to grow and expand into the 3D world we need a 3D sonic game with speed as the focus, this gen we have more then enough experience with Cameras to overcome the issues that plagued SA2, originally developed for the DC, and can pursue it rather than focusing on something else like fighting or 2.5 D because 3D speed platforming is too hard :/

And for those suggesting, this be the direction Sonic should take, all I'm saying is this can be another branch. SOH Episodes was technically the last series to come out. Why not try something new?
