[SKyOdin]

D&D 3E and 3.5

D&D 4E (current favorite)

D20 Modern

Iron Heroes

Alternity

Champions (not sure on edition, 5th maybe?)


I haven't been playing as long as some other people, so I don't have as big of a list.

 

[Gilladian]

I'm not gonna try to list everything; I can't remember them all. But a few things I know I've played that aren't on other lists (or I overlooked them) include:

Space 1889
The Fantasy Trip (actually helped playtest the first version of this game)
DragonQuest
Metamorphosis Alpha

We played just about every version of DnD, starting with the white box set, and almost all of TSR's games (except Alternity).

Many versions of Traveler.

I wish I could think of all the other short-lived games I've played. There were many back in my days of hanging out at the game store every weekend!

[Umbran]

My shelves have a couple dozen different tabletop systems - and that's not counting different editions of the same game, and the various systems I've played for which I don't own my own copy of the rules.

So, a bunch.

 

[Holy Bovine]

Oh my. I'm sure to forget about as many as I list but here goes

D&D (in just about every incarnation except OD&D - just never could find a cheap copy of it )
Traveller Classic
Thieves World
Shadowrun
Cyberpunk
Vampire

Silver Age Sentinels d20
Dragonstar

thats about all I can remember at this point. There are probably a dozen more that I played but don't remember the names of. Not a terrible list for 25 years worth of RPGs.
