Branching dialogue tree, different choices/chances of success based on charisma and speaking skill.
Poor INT will NOT affect your dialogue choices.
They figure that a crit on the eye will gib the head anwyays so probably leaving that out. Groin shot is a maybe.
Weapons have decay. They are repaired using
the repair skill which requires weapons of the same type to get parts
from. Weapons decay has many effects such as Rate of Fire, Cone, Damage
Towns and Buildings are zoned like in Oblivion (load times between each, etc).
Other factions: one of the radio stations mentioned by in game dialogue is apparently run by The Enclave.
So no dumb dialogue, options based on charismatic persuasion rather than intelligent debate. Speech appears to be a roll rather than opening up new options.
Yeah, that's a cause for concern and one step towards 'generic RPG/FPS' and away from 'Fallout' (though I'm still more concerned about the forced Father/'best friend' thing and the seemingly clear-cut good and evil stuff). No more blinding a deathclaw, either...
