SuperStars was made by Arzest so it's not even a Sonic Team game either.
Pocket Adventure is interesting but too much of a rehash of Sonic 2's levels themes and Sonic 3&K's ost. It plays decently but the Sonic Advance games were the first handhelds to finally give something since the GBA was powerful. I'd still love a true Sonic 8-bits collection though.
Even outside of the price the 3D models were kinda bland when even Generations on 3DS had a better shading. Everything looked like toys there.
On a side note: why is this game making callbacks much better than any modern Sonic games (Frontiers and Generations included)?
