Oh, I hadn't considered using the visitor controller to block the townies - that's actually a good idea. However when I used it I found some NPC's get banned from a lot by default, so you have to pull it out on every single lot to set the allow/not allow. I might give it another whirl, though.

I don't play with creatures enough, so I made the 50/50 chance to get some variety ^^ Really a matter of taste.

I don't really use pet careers either, but in case anyone wants em, they're there.

I like the early stage money sources, more added realism :) If you want to go for really really pernickity realism I guess you could prohibit selling into nowhere altogether, but with so few customers at the start that'd be really quite difficult. Just different flavours of playing.

Limiting the purchase of buy mode items is another great idea, but I'm not entirely sure how I could put that in ruleformat :) I really like it though.

Nice to hear about your take on it, so thanks! :)
