I got to play Houdini recently for the first time at length.
I liked it. Enough that I would consider buying one.
Problem for me is that I have so many games, I don't think I could find a spot for it in the space that I have. There are so many good games, and while I would definitely consider one if it came up at a decent price nearby, I already have a bunch of games I can't fit in my basement that I don't know what to do with, so adding another just seems silly.
