I played this game straight after playing fallout 3 and i cant get enough of it. am on my 8th playthrough and i still find more things i want to do in the mojave. for a game that took around 18 months it has the most compelling story in the whole franchise{sierra madre is hard as hell but that adds to the immersion}. also the addition of new mechanics like different bullet types ,gun mods ,crafting and new recepies blew my mind.
