Open world + monster = SKYRIM
half-life and skyrim probably are more 'sensible' ones from the lot of monster-slaying games
some other good ones that i remember are 'undying', 'dead space', 'painkiller', 'the shadow of colossus' (PS2), etc. there are just too many
BTW, so 'kola' now i understood, what was 'kola'
had read in some thread earlier that you were going to change your username to a proper name
