Gil is really easy to make. You just need to put a little effort in (or none if you're lucky). Don't even need to be a crafter.

I've been sitting on about 80mil for probably a month now, but over that time I've made (and spent) probably 25-30 mil (heck, two weeks ago I made 5 mil just off venture stuff). I'm not a crafter, and really should get back into it so I don't have to rely on others for my food and pots again
