Hearts of Iron 1/2/3 (go for the mods, vanilla game's combat system is kind of broken; you can easily destroy 9 retreating divisions with a dozen or two of tactical bombers, plus subs are nearly invincible to aircraft carriers).
Any turn based game, or a game that lets you pause and issue commands. I played NWN and KOTOR on the laptop and it didn't turn out too bad.
Games by PopCap, or World of Goo.
