1. Syndicate. This was a very fun game to play in its time.
2. Powermonger. It took me a bit to get into this game when I first got it years and years ago... but I really enjoyed it.
3. Dungeon Keeper --> 
Would be nice. I was not happy with Majesty2 however - and I really loved the first game. Then again - I would be looking for a spiritual successor rather than a sequal to these games.
