With their inability to take most upgrades, laptops are often married to older games. In my case, this makes little sense, as I have a good Core 2 Duo processor, 3 GB RAM, and a decent nVidia video card. Oh well.

My portable games include

Diablo 2

Dreamfall: The Longest Journey

Indigo Prophecy

The Longest Journey

Planescape: Torment

Sacred

Sam & Max Season 1

Syberia

Essentially, point and click games and adventure games.
