Trav, the way I see it, the point of the game is not the setting, but the gameplay. The setting is just one more tool to help promote an intended playstyle. The same can be said for the sex mechanics, the barter mechanics, the relationship mechanics, the GM mechanics, etc - all this is in place to enforce a gritty, dramatic, hard-choices/consequences, player-driven gameplay.
So, in this way, the game is similar to the first D&Ds where the focus of the game is the gameplay, not the setting. To "refit" the setting,in this case, doesnt make much sense since its just broad strokes intended to be more defined through play, and will be different from group to group.
About the Sex mchanics, they are in place to help convey the sense of
scarcity the game aims for, and make it a scape valve, or a barter product. (
" I need a bodyguard for the next meeting, but have nothing else to offer the Battlebabe.." ). MY group didnt feel confortable with it though, so we simply ignored it, and we didnt regret it, since there are other things in place to enforce the scarcity.
Got it?
Take a look at the game
classes and see what you think. They say a lot about the game.
