Mass Effect... wait I have played that? Well if you include doing the opening chapter and then wandering around for about 5 hours to random planets and driving the Mako around dull terrain looking for ore until I get bored... then sure I've played it. What I should say is Mass Effect 2/3... and it's YOUR FAULT ESCAPIST!
I really didn't want to spoil the games for me or anything, I didn't want to know every possible nuanced aspect of each character, their loyalty missions, the suicide mission, the identity of the shadow broker, what the three colored endings meant from 50 different angles, why Ashley, no Tali, no Jack, no Krios, no GARRUS is the best romance... I don't ever need to play Mass Effect 2 and 3, or even finish 1, because thanks to this site, it's like I've played it 50 times already and am sick of it.
Good job Escapist, good job
I would say the same for Dark Souls, but there's not much to ruin there of course, and most of the chatter is about it's gameplay or how it handles world building.
Thankfully the only thing I've heard about Dragon Age Inquisition so far is to get out of the Hinterlands (I really should go back eventually...)
