This is a long intro to saying that Ground Floor has little wooden cubes and disks and uses a worker placement mechanic, but the mechanics' tie to the theme (building a company) is well thought out and I really enjoyed it.
It also has some other mechanics in it. Its got a widget engine in there as well (not uncommon in worker placement) but I felt a bit of tableau building going on as well. One aspect of the game is that you can upgrade your office space as you go and that gives you better / different capabilities. So as the game progresses each player has very different capabilities. Also, that tableau -- your office, is where 99% of the victory points come from.
Perhaps no higher compliment to a game than that I really wanted to play it again. But the night was late and I had to go home but I look forward to more plays.
