dungeon keeper 2

players take the role of a dungeon keeper, building and defending an underground dungeon from the would-be heroes that invade it, as well as from other keepers. In the game's campaign mode, the player is charged with recovering the portal gems from each area in order to open a portal to the surface.
This game runs superb in my netbook and I think in every other netbook also.

resolutions issues on netbook gaming

For many games, 1024*768 is the lowest resolution they can go. Since 1024*600 is the default resolution for a 10.1" netbook, those games are resulting on a netbook unplayable

Main reason that many games do not play on Netbooks

Netbook incompatibility on playing games
The main reason a game may not play on a netbook is due to the small screen size and the limited available resolution available on the tiny netbook screen. 

For example, if a game has been designed to fit a 1024 x 768 screen and the netbook doesn't provide this size, an error may result and fully depends on the screen size/resolution that the netbook provides.
