Finishing the last Mass Effect game was both so ridiculously exciting, and profoundly sad. I would love to play something in this 'verse. I play fem!Shep; paragon, with a healthy smattering of renegade interrupts. Earthborn, War Hero, Soldier/Vanguard. I romanced Liara T'Soni for all three games, so I would be thrilled for a Liara, but I would honestly play against anyone. Romance, friendship, whatever. I have a few ideas for alternate ME3 endings, if you'd like to consider those. Or something that takes place during one of the games.
Pairings I've considered with Fem!Shep, but am not limited to.
Liara
Kaiden
Miranda
Joker
Samara
