As is the case with most mmo games there is a need for diversity options among players! and while weapons and armor might serve in part to set characters apart, typically mmos have selectable character bases, such as origin and archetypes. why not include Super Mutants and non-ferral Ghouls as origin bases. With fallouts growing folklore as to these species, players could develop their different roles within the wasteland (and its history) amongst them and perhaps wage player wars among segregated or desegregated clans. as to archetypes the system would most likely be less complicated basing around skill sets like unarmed brutes, heavy weapon tanks, light fire arms laser or plasma infantry, long ranged sniper, explosive artillery & fortification(traps), and lastly a melee Calvary. ( it's my opinion though in a survival based video game each character would be in charge of their own health i.e. no medics!) Naturally there could be factions within species i.e. night kin supper mutant, Independent human F.O.A. B.O.S. N.C.R. Legion or enclave. I hope Other die hard wastelanders like myself will comment on these suggestions so that we can contrast for developers what we would like to see. This game will either be the best ever of its kind or not meet expectation so i hope its not to soon for its development!
