then play dragon age origins first. u should get the ultimate edition fairly cheap.
it is a hard game, and combat isn't special. but the story is great. game of thronish but more fantasy. grat lore and character interctions are top notch.
if u get it on pc i recommend u intsall mods that enhace graphics and character models
witcher game re great too so u cant go wrong.
i recommend u get witcher 1 and dragon age origins both. the cost of both combined will be less than the new versions. and dragon age origins alone will give u 40 hours of playthrough on ur first time. and that is not even counting the expansion pack and other dlc included in the ultimate edition
