Favourite games of all time:
Freespace 2
Homeworld (the original, the story was awesome!)
MOO2 / GalCiv2 (similar, but different, games, that are both totally great)
Half-Life 2
Lords of the Realms 1/2 (#3 is bullocks)
The Stronghold series (castles!)
The Total War series (Come to me, Medieval 2!!!)
X-com: Apocalypse (I've played this game soooo much...)
Tyrian 2000 (best vertical scroller shooter ever)
Raptor (second best vertical scroller shooter ever)
Need For Speed 2: Hot pursuit (the original cop vs driver, + you could drive busses down ravines)
Dune 2
Command & Conquer (first one, another classic)
Elder Scrolls: Morrowind (better than Oblivion in some ways)
Starcraft (Zerg VS marine! Fight!)
And so many more I can't recall off the top of my mind... the other day I was cleaning the PC room and I realised just how many game boxes I had laying around.
Then I did a quick average of all the games and of how much I paid for them. In short, I could have bought a nice car if I had never bought any games.
Bug games are better
