DEFINATELY more weapons/armor-especially those new weapons being added by various Russian modders. More drivable vehicles-and the ability to use the machine on the the APC or even *gasp* a drivable tank!
More of an emphasis on factions-rise through Duty's ranks by leading raids on various Freedom bases, or become Lukash's "enforcer" by assassinating important Dutyers. Try to make it feel like you're a part of the faction. Maybe even the chance to rebuild Strelok's group from your selection of stalkers that accompany you on raids, or attack Duty/Freedom on your orders, etc.
Perhaps that could be accomplished by tying dialogue to scripts governing faction relations? I'm no modder (as you can likely tell by my list of wishes above :wink:) but say you did it like:
Condition:select topic "attackDuty"
Effect: Relations with Duty = -100
Effect: Strelock_member_1 (this will be someone you recruited)and strelok_member_2 goto location: Bar/Duty outpost@ Garbage
^Just a concept, as you can tell from the way it looks nothing like the S.T.A.L.K.E.R. scripts
Wow. I think I overdid it.
