I thought the section where you had a chance to talk to all of the major characters at base was just a great set up. I'll just try to pretend my Shepard died on the way to the Citadel and Garrus managed to finish the job. There was no child god that made him choose between 3 shitty endings. The Reaper's just blew the fuck up in the best fireworks show the Milkyway has ever seen.
i thought it was such a step down from 2's suicide mission or taking back the citadel in 1 though. The whole ending sequence felt rushed and unimaginative.
