A couple of things thus far: If the game exists on the Master System, A) I likely already own the SMS version and B) Unless there are drastic changes (i.e. Sonic 1, where there are significant graphics and level-layout changes) then I'm not interested in it. This is a list of purely GG exclusive titles. Also, I will not pick up anything unless it's CIB.
That said, I'm damn surprised at how cheap it is to collect for the game gear! There appears to be little to no collecting value for this stuff, even boxed, as it's all gone for dirt cheap compared to, say, MSX or Famicom stuff. Here's what I've got so far:
Samurai Shodown
Fatal Fury: Special
Fantasy Zone Gear
GG Shinobi II
Tails adventure - I also have the US version
Shining Force Gaiden 2 - I also have the US version
Gunstar Heroes
Ristar
Tempo Jr
Coca Cola Kid
GG Aleste 2
I also bought a boxed game gear console, just so I can have a boxed GG to go along with these boxed games. I found the same model and box that I got when I first got my GG new:
I'm considering Panzer Dragoon Mini right now. It appears to be the priciest game gear game released. I've also picked up boxed copies of all the US Sonic games (and I still had Tails Adventure from when it was new).
Is there anything major or obvious missing thus far? Again, GG exclusives only, so no stuff like Battletoads or Earthworm Jim, as I have those games for my SMS already.
