OK, last night I found this demo for an upcoming game called
Hotel Giant. From what I've played of it, I think this is the best tycoon-like game since rollercoaster tycoon. Basically, you manage a hotel and try to keep your guests happy. The demo only gives you the 1st 3 tutorial missions, so you don't get to build much else besides guest rooms and a lobby. It is a lot like a cross between the house-building portion of the Sims and Simtower. You place all the different objects in the guests rooms and listen to your guests complaints. The graphics are in full 3d and look pretty nice. Anyone who likes tycoon games should definitely give this a try.
