I've been building up spare keys for a while, and the autojoiners are suspended right now, so it seems like a good time for a big dump.

This game is a pretty standard example of an economy simulator game. Buy low, go somewhere else, sell high, make enough money to do the sidequests. I like this genre, and this one's alright. There are better ones, but if you're into that kind of thing, you'll probably enjoy this one.
