Yeah, so just one synthesis ending.. makes sense. Couldn't really focus on the destroy endings differences.. that's such a mindfuck of a video! Hah. Anyway, I stand by my decision as synthesis being the most Paragon-like ending. It's in line with the Geth re-writing being the "good" choice (poor Tali), it has the least collateral damage, technology remains advanced and likely even more so and it ends the war with the Reapers.
With that in mind, I still was okay with the ending since I chose that route. I got a bit of a kick out of the fact that the post-credits bit means we'll probably play as Shepard again in Mass 4. I was expecting it'd just be in the same universe at a different time period (maybe pre-Genophage or something) with completely new characters but it seems like that won't be the case in all likelihood.
