I kind of fell out of Spore some time ago, but a buddy of mine recently picked up the expansion and after having played GB:TVG with me, he's gotten really hooked on Ghostbusters. So much so that he created a GBs inspired adventure to play featuring a lot of the things I made. You have to have both the expansion and the cute and creepy parts pack for it to work. I don't have either of those things, so I can't say myself how good it is, but he has been mentioning some of the things he's been doing or the stuff the characters will say, and I think it sounds pretty neat. So anyway, here's the link…
EDIT: Patch broke the mission, here's the new link…
