Sonic Advance's graphics are good, but imagine what the games are going to be like a few years down the line, even the the GBC they were pulling out the stops right towards the end of it's life
It's a good GBA game, but nothing compared with the Mega Drive (or Genesis) sonic games.
It's too short, but it's good to control all those characters.
Did you know about the way to make Tails run behind sonic???? (NOSTALGIC)
