I'd assume Mononufu or w/e it's called gets there eventually. Same with Kingdom of Lust. (which is a clone of a an entire genre of games (clash of clans, etc.) with a similar "builds up to take F'ing forever" mechanic.)

(I think those games *tend* to limit you to building 2 structures at a time w/o paying though, but there's a WHOLE lot more structures in need of building)

And yeah, the percent for drops go way up. Map 1 the two items are 10% and 15%. Map 39 they are 40% and 38%. But in either case they are common trash feeders.
