At the very least, the hope is that the games that do come out are long, fun, and of high quality. The game involves lots of searching, exploring cool-looking environments for emeralds, and meeting many interesting characters that advance the storyline. Like I said before, if you played the first Sonic Adventure, you'll be able to get right in to play. You use the analog to move, and the buttons a, b ,x ,y are the action buttons. The triggers are used for camera angles.
Controls are decent, with nice response from the buttons and tight movement.
You can play as either Sonic , Knuckles , Tails or his evil twin. Sonic searches for the chaos emerald and wants to stop Dr. Robtnik from destroying the world. The character can climb walls, fly, jump, swim and of course kick some butt. In game puzzles are fairly easy, nothing new here. None of the puzzles are very hard, and the game isn't very long, although playing with different characters lengthens the adventure.
