What was your first GOG purchase and have you played it all the way to the end yet?
Mine would be ROA 1-2 and No.

Freespace 2 and free FreeSpace, I didn't finish it (I finished the retail version when it was released).

I've bought four games the first time. Fallout (not finished yet), Stonekeep (not finished), MDK (finished) and Broken Sword 2 (finished).

Jagged Alliance 2, and no. But thanks for reminding me, I'm quite close to the finnish.
Ups, I mean, finish. I don't mean close to the people living in finland.

Gog had a sale for the 3 Fallout games. I finished the first, but I never got around to Fallout 2 or Tactics.

Fallout and Fallout 2

Prince of Persia: Sands of Time
Bloodrayne 2
In Cold Blood
Sanitarium
Advent Rising
Beneath Steel Sky
Earthworm Jim
Gabriel Night: Sins of the Fathers
Once I joinen gog I became extremely hype, so don't be surprised.

Same here, both first games and status... in fact, I don't think I have actually finished any of the games I've bought from GOG, which is really unusual, since I am normally a bit of a "completionist" with my games. GOG has turned from a game player into a game collector.

According to the my list, I first bought Fallout 1 & 2. I haven't finished them yet, though.

Duke Nukem 3D.

You forgot to add "yes, many times".

UFO Aftermath and no i haven't finished it. I didn't finish it because it got boring after a while but it was worth the $4 i paid for it.

Redneck Rampage

Hmmm... I got my first gog with the closed beta 1+1 deal, so I actually got 2 games. I think it was... Hmmm... Damn, that was along time ago... Yea, I think it was Fallout 2 and something I didn't play yet. But I'm not entirely sure what :D

Disciples was my first purchase after downloading and finishing Beneath a Steel shy the day before. I have yet to finish Disciples mainly because I'm stuck against an insanely powerful and annoying opponent who won't stop spaming all my parties with spells when ever they leave a castle.
