Finished the game last night.
Loved it up until the last 15 minutes. The ending is horrendous (ANY of the endings suck, they're all virtually the same anyway). No matter what it's a phyrric victory. If your Readiness is high enough, that is, if you played enough multiplayer (which is pretty fun actually), Shepard might live at the end. I didn't get my readiness high enough apparently. Still, it didn't bother me that Shepard dies, but that no matter what the entire mass relay system is destroyed and every alien species' military is essentially stranded on Earth indefinitely. And for some reason the Normandy is zooming through space and crash lands on some random "garden world". Wasn't the Normandy just fighting Reapers above Earth moments before?
