Torchlight

Cool Diablo-style action RPG that scales well for low-end machines. It even has a “Netbook Mode” check box in the settings menu (but too many enemies on screen at once can cause slowdown if you don’t have an Ion Netbook)

7

Plants vs. Zombies

An addictive take on the tower defense genre–easily one of the most fun casual games ever

8

World of Warcraft

The world’s most popular MMO isn’t exactly a natural fit for Netbooks, but it does run if all the graphics settings are turned down.

9

Quake Live

Years ago, hardly a day would go by without enterprising office drones jumping into an intra-office Quake III match in the middle of the day. This free, browser-based version of the game is an amazing simulation, and works on nearly any PC. Play it online at QuakeLive.com.

Alien Shooter 2/Zombie Shooter 2

Part of a line of new 2D, top-down (isometric, actually) action RPGs, these blood-soaked games are great fun, and easy to play even on low-power machines.

11

Fallout/Fallout 2

Sure, Fallout 3 is one of the best open-world RPGs we’ve ever played, but the original 2D Fallout games were also great, and known for their sly humor and engaging characters (even if the control interface seems needlessly clunky today)
