hi.
as a casual player, I'd like to suggest something that emphasize on more faction based pvp.
but with NPC faction, not PLAYER factions..
I (and many others I'm sure) don't have time to make friends in online gaming, and my opinion on reload is that people that belonged to certain player owned factions were very advantageous.
Nothing wrong with that. There will always be favor to players with more time on hand, but my suggestion would be emphasize more on NPC factions..and let there be war (with rewards).
so for example, you join Brotherhood / Enclave factions, and let there be a crusade in certain area, once a week or something on a specific location (with rewards). You don't need to have 10other fallout friends, all you have to be is belong to either faction and just casually participate in the warzone in the right time. (the location should only be available maybe during the war time)
same can be done between Raiders+Slavers+New Reno vs. NCR rangers, etc etc.
this idea is based on an MMO RPG called Helbreath. Cheers.
