Thought it might be cool to make an "official" list of published games for the Lynx, based on a discussion we're having on AtariCentral...Published games means properly licensed/produced games. That means Loopz, RR4WD, Lynx diagnostic cart, etc. don't count, even though several sources have sold copies of these games in the past. Even "genuine" protos, like AvP or EotB, while great to have in your collection, don't count.
It does mean an odd game like Blue Lightning Demo does count, because Atari sold it directly to consumers before they self-destructed (I wish I would have bought a bunch of those, only $4 each at the time!).
CM2:BT doesn't count; it's an expansion and not a stand-alone game. Neither would other accessories like the Lynx to PC cable, comlynx cable, sun visor, battery pack, game wallet, etc.
T-tris would count twice, because there are two versions. Technically, you could even count the original stand-alone BLL cartridge Bastian made, but he only sold it to a few developers (like me), so it was never a "consumer" release.
Ponx only counts once. I did make ~80 EPROMs of Ponx before I realized I could add one more simple cheat. I still have all 80 EPROMs (not on carts, just the chips) sitting in my basement, maybe someday I should publish it as the "original" version of Ponx? 
Hyperdrome definitely counts, because it was developed and published by Telegames.
LGSS counts, because it is a published cart. Just a very limited use one. This is no different than SFX, really, which also is not a game, it's a tool.
So, here is what I think is the list of published games:
