Portal 2
Freelancer
Uncharted 2: Among Thieves
Civilization IV
Final Fantasy VII

Something real life, something fantasy, something sci-fi, action mixed in with "play at your own pace", some complex, some simple, some old, some new, some funny, some serious, some story-rich, some fairly story-absent... etc. Missed out on racing (Mark Kart most likely) and sport (Football Manager!) because, well, I could only list five games and in the end something had to give.
