During my two month stint in SWTOR I enjoyed the story element.
I picked up KOTOR on Steam for $10, but didn't really get in to it (maybe I didn't give it enough time or am too much of a graphics snob).
A couple weeks ago Amazon had Mass Effect I and II on sale for $5 a piece. I snatched them up in an instant.
From the moment I picked up Mass Effect I was hooked. I liken it to playing it to playing those great adventure click games from the likes of Sierra and LucasArts. Games such as Space Quest, Leisure Suit Larry, Maniac Mansion, Full Throttle, Indiana Jones and the Fate of Atlantis, and The Dig.
I played through Mass Effect and am now in the middle of Mass Effect 2. I can definitely see the Mass Effect and KOTRO DNA imprinted in SWTOR.
I'm thinking of trying out Dragon Age after I get done with Mass Effect 2 should I not succumb to the hype of Mass Effect 3 in a week.
