I don't have an actual specific count (there are gaps in my spreadsheet) so I played it safe and didn't oversell it. It's probably in the 300s somewhere but that's counting environmental stuff so I decided to round down.
Yes, I have my best man on the job so there should be art for all the playable characters!
Is anyone actually "sold" by those number factoid things? My eyes just glaze over when I see them -- telling me the quantity doesn't tell me anything about the quality. The numbers tend to all blend together once they reach triple digits or so anyway. I dunno, maybe it's a roguelike thing? I've seen lots of RPGs on this site do the same thing, though.
