YEAH! Ash gets it!! Sonic Triple Trouble, but also Sonic Chaos, are the best portable Sonic games, hands down. Also Sonic 1 still has its charm, 2 is only flawed because of the screen space, but is infinitely better on the Master System.
Best Game Gear Game, nothing honestly comes to mind outside of Sonic since, despite owning a Game Gear, I only owned Sonic games on it hahaha. Really enjoyed Tails Adventures, but Triple Trouble takes the cake.
I did get the GG Aleste collection when it came out, though, and let me tell you, the GG Aleste games are spectacular. You’re gonna have a real good time with them and GG Aleste 3 if you’re a STG fan. Amazing set of games, my goodness.
