I think i qualify as a huge fan :).
KotoR 1 and 2 are still great games, Played Dark and Light side, on both genders.
I've played through Dragon Age: Origins with all classes/races/genders, and all romance options, just to get little changes of dialogue in Wardens keep.
Around that time i've replayed Mass Effect about 5/6 times, both genders and some romance options.
I can't count how many times i've played Mass Effect 2, full paragon, full renegade, all romance options through both genders, and replayed the games when the new character DLC's came along.
Around that time i got my own family and responsibilities, so the hardcore powergaming had to slow down a little.
I played Dragon Age 2 twice, Isabela and Fenris romance.
Mass Effect 3 though, responsibilities or not, i must have played through that quite alot of times, both genders, all romance options, replayed for Leviathan DLC, replayed for Citadel DLC. Still didn't like the ending.
Only played Dragon Age: Inquisition once (Pentagast romance), its a great game, but damn its huge. The prospect of replaying that just didnt pull me back in, and i just looked up all romances and stuff on youtube.
SWToR, all classes are level 65 apart from the imperial agent, but i stopped playing.
Loved Baldurs gate 2, but i only finished the game once. Was pretty young when i did.
Never played Jade Empire, never caught my attention.
And oh yeah, i have the Mass effect action figures, and a small normandy.
There, my nerdcred, i had way too much free time.
Since i see the romance arguments already: I ship Morrigan, and i'm a Talimancer.
