@Rannah: I love all your screenshots, but especially the bottom one of Blackwall. ♥ Those are some awesome crisp graphics.
So hey, I read a few pages back that someone was starting Mass Effect and I still have the option of playing it too (for the first time).
I can either play Mass Effect 1-3 or Dragon Age: Origins and 2. Any recomendations of which one first? And of these games, are there any romance options to look out for? Since you guys seem to have impeccable taste and all 
To play these games for the first time...I'm so jelly! I'd recommend sticking with DA for a bit, because it's a chance to go deeper into territory you're already in. ME is a fab series though-I've been jonesing to replay it myself.
LIs in DA: I think they all have something to recommend them. The only one I didn't complete was Morrigan's, and that's only because I don't have an easy time playing men. I'll give my capsule reviews of the DAO LIs I completed the story with.
What I liked about Alistair: he's very detailed - he has an Achilles heel (maybe more than one), a history that you get to hear about, moral blind spots, as well as endearing traits, all while being a modest subversion of quite a few fantasy tropes. To me, this makes him pretty memorable, even when he's not likable. And in these games, I always favor the former over the latter.
What I liked about Zevran: hidden depths, wit, and an accepting personality. It's been a while since I've played, but I feel like Zevran wasn't as detailed as I like LIs to be, but what is there is engaging, and you can have some great convos with him about stuff. The only LI that my husband and I liked. 
What I liked about Leliana: she has so many facets, and she is so, so sweet to you. I was intrigued by her, and as a somewhat mystically inclined religious person, I was thrilled to meet one in a game (to say nothing of being able to romance one), especially since that aspect of her is painted as something that makes her more formidable and appealing, not less. That's unique, imo. Her history was also interesting.
Honestly, DAO's LIs were all pretty damn good, imo.
