I'm on my fourth generation with just the one slot going. I've been playing for a few weeks now, not sure exactly. I think I've earned around $72000 all up but I currently have almost $45000. I've bought all except two of the home improvements (treadmill and pinball machine left to get...just seems like sooo much money to spend on something that I'm not sure of what it gives my peeps) and I'm currently saving the final career room upgrades. Oh, and I'm starting my collections again (even though I only completed the coin one) because someone offered to buy them and I thought why not? It's not like I'm not going to keep continuously playing and therefore keep collecting.
