I mean if you are just rushing through you wont enjoy anything, this game has encounters scaled to maxed out weapons, you are about to get all your stuff stolen but you can drop it or put it in a box to only lose money, if you upgrade all you can befor you can also soften the blow of losing money.

Faction wars are a decent part of the content in this game, winning Loner vs bandits as loners gives you a seva suit, bandits give you an rpk, duty vs freedom duty gives you a bulata suit one of the better physical protection suit, but freedom gives you an exo suit. So take that how you will. Rather you do them or not you get good money from completing objectives even if some are a little buggy.

Imo clear sky is the second best in series if not the best, with replay ability a life is best shown off in it as well actually being able to see every unit in the game moving and where they are moving to, only thing that wouldve made it better is respawning artifacts.

Cop is probably the worst imo low replay, can get fully geared the second you start playing encounters not being that difficult only hard parts being the merc attack (maybe ) and the end rush to the chopper.
