Hey lads, first of, sorry for my realy bad english and grammar, doing my best.
Ok im thinking of buying this game, but im not sure if im gonna take just sins, or any of the expansion or the trinity.
So my question is what kind of expansion is those? is it like ''crysis / crysis warheads, where i simply got 2 .exe so i can play two different game/story.
Or is it more like ''Eve online'' expansion'' that add stuff to the original game? and if its more like this what game should i start to get it all? sins, diplomacy, entrechent or trinity? if i now get several .exe??
hoping to get some answers soon so i can buy this game 
cheers!
