What games do you enjoy on your laptop? Generally speaking, a laptop game for me needs to meet a few requirements:
1) Playable with minimal mouse movement, or at least non-rushed mouse movement. Starcraft 2 wouldn't work, as an extreme example, but worldwide football manager does.
2) Playable with minimal system requirements. Laptops are getting more powerful, but the average laptop still isn't up for playing Left 4 Dead.
3) Playable without a constant internet connection.
4) Playable in short spurts.
So, without further ado, my favorite laptop games:
GTA 2. Very arcade and involving, but playable completely with the keyboard.
Peggle. You can take your time aiming, even if you do use the mouse.
Plants Vs. Zombies. It does require some active clicking on the sun drops, but in general seems to play just fine.
Worldwide Soccer Manager. I suck at it, but I do enjoy watching my soccer teams fail miserably.
Civilization 3, or 4. Lots of depth, easy to save and resume later.
So? What about you?
