I remember that it was a pretty terrible game that infuriated me to no end. Only two maps, nonsensical mechanics, tons of bugs... it was a great idea for a game, but just so poorly implemented that it made me cry.
I mean, come on. Secret agent sneaking around a perfectly legitimate hotel island resort shoots the desk clerk in cold blood, and the security guards attempt to subdue what appears to be a gun-toting lunatic. OBVIOUSLY THAT MEANS THE HOTEL A FRONT FOR A SUPERVILLAIN. FULL INVASION OF THE ISLAND! GO GO GO!
Crap like that just completely sucked the fun out of it.
Now, you want a good Dungeon Keeper style game? Go play Startopia.
