LMAO if anything the censoring of this game has made me discover 'inappropriate words' in all sorts of new places that I'd never considered before...

As for the Tree, there is only one case that its worth considering going beyond the 1000 point threshold, and that's when 1) you have a ton of ingots/coupons, and 2) you really really want one of the rare ninjas that u can get frags for in the final level tree (e.g. ssn itach frags).
