i really like this thread! i was going to read it all, but by page 19 I started to wonder just how many pages there were....boy am I glad I decided to skip here! I assume you're doing games now, but I can't think of a Z, so I'll jump in later.
Zoo Tycoon (sorry - it is a computer game, but I couldn't think of anything else). Somebody pick some to to fast - I don't want to go into withdrawals here! I am fresh out of "fresh" ideas.
