: Looks like a definite preference for lava environments first, and sewage
: second, from the posts here, and I would tend to agree!
Ah, you'd think so, but you're only half-right. From a mapmaking perspective, I LOVE lava environments but absolutely despise making sewers. There's so much versatility with the M2/Inf lava texture set that you can make a slew of different environments - caves, "facilities," even spacecraft can be done with it. But with sewage, there's not much you can do except make sewers. 9 times out of 10 I'll take the Jjaro set (which is very similar), except when I REALLY need to make a sewer.
: Which big secret are you talking about? There's more than one ;^)
Whoops, I forgot. I meant the universal switch that opens all the gates at the same time.
