Oh man...I've been playing PC games for over 20 years - there's no way I could remember all the ones I've beaten 😀

I know. It's pretty sad that we can't remember something as simple as beating a game. Stupid human mind.

That gives me a good idea. I need to add a flag to my personal games collection DB at my homepage to mark which games I've beaten. I've beaten close to half of them.

Similar to HunterZ's response, I have been playing computer games since I got my Atari 800 in 1982 so it's hard to remember all the ones I have beaten. I would have a much, much larger list of ones that I started and never got around to completing.

What I remember off the top of my head that I have completed:

Updated

People: perhaps you should record your runs, and send them in to Speed Demos Archive http://speeddemosarchive.com/

And see, if you can beat the times of other people 😀

Added F.E.A.R to my list.

For some reason I could put all options up to max except for the textures. Any time I used higher than minimum textures the game would bog down in certain places....I'm talking lower than 10fps.....Guess I won't be playing the expansion until I build my new computer.

yea i know, higher texture settings eats alot of graphics memory. more than any other similar games i had played that time.
on my gf 6800 ultra (256mb), i can play with highest settings but only 1-2 levels. after that, the game access the HDD (swapfile) frequently...
i got better results after disabling backround programs like virus scanners and defragging my HDDs.

i can recommend the expansion. 😀
alot of great firefights and some surprises in the higher levels, but with an open end in the storyline. i hope the developers didnt put this game to rest after that...

Added SACRED: Underworld

Updated. Added S.T.A.L.K.E.R to the list.

Hmmm, could have been a great game. It's worth playing but there isn't enough of a story worth caring about. Most of the missions I didn't even bother to read the text and the ending sucks.

It's definetly worth playing if you like FPS games though and you should definetly install the faiakes mod.

Oh man, I couldn't possibly recall all the games I've beaten, and I won't even try. I'll just post the single one which was the most satisfying to beat:

i really enjoyed playing stalker. but you only found out whats behind the whole story if you do the secret quests (find the monolith base and talk to the leader). i like also the fact that the game has 7 different ending sequences, but like dosfreak said, they are to short and not very impressive.

actually playing Silent Hunter 4: Wolfes of the Pacific. nice graphics and alot of bugs even with the 1.2 patch...
