I keep meaning to go play Dungeon Keeper 1&2 as they are meant to be real gems.
I'm looking at getting a laptop soon so I can play games on the train to work, and these games are the sort I will be playing.
They are awesome, I suggest you do try them. If you ever do though, make sure you play DK1 first. Otherwise the far superior graphics of DK2 will just ruin DK1 for you.
