I've came to similar conclusion to OP's point of view. There is to big generalisation of stuff in Fonline - same looks, skins, weapons, items.
When I go to city map to scavenge I would love to have big map, full of shelfs, crates, pack of rubble to search for some goodies - hundred of diffrent things (...discribed as junk). Sadly making such feature would require shitload of time and amount of work so there's nothing to really bitch about.
When it comes to character looks I'm looking forward for 3d models... which will hopefullly get implemented this year :/... maybe.
Untill then, can someone tell why the hell mods stopped giving out skins? I know they don't support every weapon but that's somehing we can give away for a little bit of unique touch or RP buff.
