Its as simple as that, you can show folks what your old house looked like while throwing a party with as many or as few guests as you want.
This way anyone who misses their old house and visit with it again, and TS wont have to re-do any of the old housing to make a few folks happy.
I used the Large Alakol model house for a party and it was a blast! Even RUBE showed up, so you know it was a good time if stuffy RUBE came out to a party.
Extra bonus: you host a party in a house thats not yours! You dont have to worry about the guests eating the fish out of your fishtank (happened to me), doing bad things in the coat closet (did that at someones party, naughty elf!) or throwing up in your pool (not saying who did that but you do it again im whupping your ass).
Extra extra bonus: maybe there could be options when you start the pack to choose house type/location so its just ONE party pack to buy, but with little check boxes. Maybe a feature to stick a house in Toxic Moon as the back yard so you can go flying up in the air (which I enjoyed).
Ok I had my say so now everyone post and scream at each other and stuff.
