Tails Adventures is also my favourite one, I played it like 52000 times on the PS2. Fan games: i'd say Sonic Time-Attacked, that game has the classic feel AND the 2nd boss level is really awesome, Although the boss really sucked. Enimies are ok but i think they could be done better.I made this a fav because it it has the most unbeleivable graphics. Tons of people said 8-10 out of 10 on it including myself.
