I dont think i have ever played any game where you could exploit so many things with alts. Personally i never make alts. Although other players have super strong pvp build together with excelent crafter and i have only my one weaker all purpose char, it is still more like cheating for me.
It is not impossible to make one character and play whole session since crafting requirements are so low, but people are still making ultraPVP builds - ok, they want to be fighters so they shouldnt make alts, RP - but alts will be always, sadly, we cant bound one character per IP since there's proxy etc. The only resonable solution i can think of is "to make character, you have to present his history background, write a story about him which explain why is he build in that way he is" and that should be confirmed by GMs and then you can get to the game (idea from Ultima), so then no chars type "crafterBG" "slut1" "mule1" "taxi" will appear and it will take some effort to get character which will minimalize alting (or make alt makers creative) but i think we got too low playerbase for such moves - it needs hard work of GMs and it would make server population even less than it is now.
Pissed of npcs dont have to attack just bases, they could also attack towns under gangs control and for alts without base, npcs can hunt them in towns which are not in war with their faction. So for example enclave farmer would be safe only in places where enclave is hated.
Well, it would be hard to implement to set NPC "bounty hunters" for every player that is hated to wander around wastelands, and there's already "shoot on sight" when you enter encounter or enter base with "hated" reputation.
But if there is no better way to limit farming and people will call for limiting it, it will lead to less lootable npcs and i dont like it. I just want to get that half broken minigun from supermutant which turned my armor in rags. When npc stops dropping their equipment its like they dont exist. You could just erase them right away and let players join npc fanctions, take equipment from them and do missions for them. This way when players farm BoS, they actually farm on other players which are not so dumb like npcs.
Ok, maybe making NPC non-lootable is a bit drastic, but encounters should be limited (idk, lets say rarity of meeting some kind of NPC is increasing as you kill more and more soldiers (Unity got 200 soldiers around wastes, and %chance to meet them is high, but while you kill 100 the % is decreasing and replenish with time), also, there shouldn't be Highest Quality Stuff available that easy way - so, if not making npcs unlootable, then the items they drop should be nerfed to something good, but not best (for ex. nerf Minigun and make blueprints for Avenger minigun, which will be as good as Minigun is now; add Brotherhood Armor blueprints(not implemented as i remember?) and make it much better than CA, CA little worse and MA MKII as well). I'm not playing often this session, but i got a feeling that not much is interested in crafting ammo, cause its much much faster to farm it. They should drop less ammo.
Towns run by players would be great and I think someone has already tried turn base into public place.
Yes, actually, i was thinking about it lot of time ago, bunker base is great place with mines and E-parts (it was session ago when i was more active) but again - you cant do a shit without GM supervision, and they're not part of the gang and they're few, interested in RP only from time to time - so why dont we have on our own territories have some powers of GM.
