So I finally gave Complete a go for the first time recently and imho it ruins these games. Dumbed-down AI, altered ballistics (varied probability to hit has been completely removed lol), lollerskates sprinting (you can cross major areas in less than a minute without fatigue), fucked-up FOV, removed headbob, broken actor proportions, increased inventory limit and a whole host of other bullshit that isn't stated in the feature list, not to mention other stuff further in that I didn't see before uninstalling this heinous garbage.
I tried fiddling with the mods - changing ltx settings to 'my taste,' but they seem to be such that I don't think even artistpavel knows what he changed. Just compare the sprinting between the mod and vanilla, laugh out loud at the motorbike-speed sprinting and note how it isn't documented anywhere (at least not on moddb). Also TELEPORTING - WTF???
Vanilla Stalker (all three of them) is one of the best gameplay experiences you can have. I'd advise playing it unmodded (especially if you like hard shooters), since Complete makes the games a total roflstomp. I'd even go so far as to say Stalker never needed improved graphics, so this mod is pointless (I know the graphics aren't to everybody's taste, but jesus christ at least it doesn't look like every other goddamn game on the market).
If you want a decent crack at Stalker, play it vanilla with a bugfix bundle (e.g. the Sky Reclamation Project). Off the top of my head, the only other mod that might be worthwhile is iron sights for pistols in Clear Sky.
The Stalker Complete thing is snake oil. You don't need it, it breaks more than it fixes and the game is fucking perfect as it is.
