Years ago I inherited my wife's family's Game Gear. After a recap, and replacing the backlight, I started tracking down games to play on it. It's been great exploring a whole library of games that I skipped out on as a kid! (I was a Nintendo kid) Now I have a nice little library of carts to play on this beast of a 90's handheld.
It's great! So is Chaos.
Weirdly though, my favorite is still the first one.
Sonic 2 on the GG is absolute garbage.
