Another mario game...another one indeed. It was one where the 3D effects of the 3DS served as a gimmick to solve puzzles. A new and interactive way of playing your games.
Sometime during 2013 I was hunting for GBA games to get and Sonic Advance...wasn't on the list originally. But I saw all 3 games on ebay for DIRT cheap and in complete condition so I went for them immediately and won them all with no resistance. I got this game for 5 bucks complete. Easily one of the best handheld Sonic games. 4 playable characters with Sonic, Tails, Knuckles and Amy. Amy's first 2D game I believe, she's pretty fun here and plays similarly if not the same as her Sonic Adventure, only in 2D. Hammer to catapult herself and bash enemies. Sonic, Tails, and Knuckles do what they are known for but they all have an attack button as well when standing still. The stages are awesome with good music and great Eggman bosses. Sadly, the special stages are a problem because of the perspective. Imagine Sonic 2's special stages but you can move ANYWHERE on the screen. Doesn't sound that bad until you actually play it. For better or worse, you don't need rings to get to a special stage, but you have to find a special spring in certain levels and jump on it to go to the special stages. They are sorta hidden so you gotta put your Sonic CD skills to the test to find them. Luckily you only need to get the emeralds once with any character and you can get to the final level. There's also a Chao Garden if you want to transfer your SA2 Chao's from the gamecube game to this for mini games and stuff. Overall, and awesome Sonic handhel game and the simplest of the Advance trilogy.
have this too
Great Game. Loved the Chao Garden. Wished the other Advance games added more to the Chao Garden rather than not doing it.
in Wii games

Best Mario Game Ever.
You either love it, or hate it, but I love it!
