User blog comment:Tiredman2/What DLC would you like to see in the future?/@comment-5503561-20120822212134/@comment-1388547-20120822221016

Sure -- a Garrus/Tali marriage ceremony (conducted by Shepard in his/her capacity as commanding officer of the Normandy) on the eve of the final battle. Highlights include helping the lucky couple select a best man/maid of honor, and seeing everybody's reactions to the ceremony -- Dr. Chakwas gets all teary-eyed (alternately, Dr. Michel looks very jealous), Vega makes inappropriate comments, the Virmire Survivor says a few words if present. Shepard can speak privately with newlyweds; if you forget to tell Tali to take her medicine and Garrus to disinfect, Tali is sick for the final missions. (Maybe apply a filter to her voice to make her sound like she has a cold?)

Yeah, there'd be a lot Bioware could do if they ever got bored with actual gameplay DLC and decided to turn Mass Effect into a pure social interaction sim...
