It was mentioned briefly in the Analogue Pocket thread that maybe there weren't enough good Game Gear games to warrant getting the adapter. This is false!! Game Gear is a neat system that sometimes almost looks like a genesis due to the number of colors it can use. The biggest issue I have with the Game Gear is its low number of sound channels, so they wind up sacrificing melody for SFX etc… really makes it feel old. Otherwise the games can be quite contemporary-feeling in some ways.
I played a bunch of Game Gear games in college, then got into the deeper catalog in the early handheld emulation days (GP32 etc), and found a bunch of real cool stuff. Here are my recommendations - if nobody else has games to add, I'll come back with some deeper cuts later! I'll just share one video per category to not overload things.
**Original recommendations**
Godzilla: Kaijuu Daishingeki - tactics game with realtime battles where you play as the monsters. Probably my favorite Godzilla game.
Sylvan Tale - very nice action RPG where you turn into animals. has an english patch. used to be obscure, but people really seem to like it now, so that's nice!
GG Aleste 1 and 2 - best shooters on the system. Compile rules.
Royal Stone - sequel to Crystal Warriors, a game which I have a soft spot for. Check the use of color!!!
Shining Force Sword of Hadja - it's a solid shining force game, that's about all you need!
Tails Adventure - you know how so many sonic games for 15+ years were like "it's sonic, but with X gimmick" - this game imagines the gimmicks at the forefront and sonic in the background. It's basically an action game that happens to use tails. Throw bombs, use vehicles, turn into stuff... it's imperfect but it's pretty good!?
SMT Gaiden Last Bible series - First last bible is an upgrade of the GBC version of handheld weirdo SMTs. also there's an english patch. Original is top down, Special is a dungeon crawler that's unique to game gear.
Psychic World - a valis-like!

**neat ports**
gunstar - it's amazing that it works at all. it's totally playable. It gets a little soft round the middle but overall it feels pretty good.
dynamite headdy - ditto, though it makes a little more sense that it works
ristar (like a cutesier version of the original, and wow, the colors!!)
Power Rangers the Movie - probably the best fighter on the game gear, though some of the SNK ports are okay
Terminator 2 Arcade - a port of the arcade game for game gear for some reason - it's a rail shooter with a machine gun, which was real fun at the time. I still like it! Really has that Euro feel in a good way
Streets of Rage 1 and 2 - they're cute ports of their bigger siblings. Not perfect, but it's more streets of rage.

**honorable mention:**
Defenders of Oasis - nice top down trad RPG but definitely feels old now.
coca cola kid - speedy run and jump kick game. it gets samey after a while but it's pretty neat, with lots of "destructible" backgrounds.
sailor moon - this game mostly sucks but it's passable sailor moon and better than a lot of the main console offerings!? and people are gonna want to try it if they know about it, so it's on here.
taz-mania - the music must be experienced.

**games I think might be cool but haven't played:**
Kishin Douji Zenki - graphics look hot, platforming looks decent?
Vampire: Master of Darkness - SIMS-developed game gear castlevania
