The end makes some sense, but a whole lot of crap is in there as well - which leads me to a point of thinking it's either 1) indoctrination and you have to pass the 'test' to free your mind from it; or 2) simply a dream as Shep is knocked out after the blast from the Reaper.
DLC will probably give us the real ending, but I have to say this:
I will LOVE DLC that adds more missions, units to fight with you, allies and crewmates, etc. I will buy THOSE DLCs...
I will NOT, however, pay for a DLC for the REAL ending of this game. If there IS a real ending, if it IS a dream or indoc happening here, then that REAL ending needs to be put out as a END-PATCH, or FREE DLC. I will not PAY for the end to a game that should have come WITH the game I bought.
As for the mind-play they do with what we currently have, it IS thought provoking, but ENTIRELY unsatisfying. For us to be expected to pay for a real end is a cruel joke.
Bioware. I love your games. SWTOR, KOTOR, DA:O and DA2... But Mass Effect is your crowning achievement. PLEASE PLEASE PLEASE don't let it fade off with a poor ending or expecting your fans to PAY for a real one. Expansion DLC for ME3 = fine, great and amen. Charged DLC for the end to see what we achieved, good, bad, horrible, glorious or anything inbetween? Never. I will not pay for that. And if that is what you expect, I'm going to be very VERY careful about your games in the future. Please don't let it end this way.
For those who liked/loved the ending as it is - power to you. But as an RPG lover, it sucked with all the plot holes, unanswered questions...
Who built the Reapers? Why? What is the REAL meaning behind the cycles?
What happened to those living on the Citadel when the Reapers came and took it to Earth?
What happened to our Galatic readiness when that event happened? It should have lessened everything with C-Sec dead or missing...
Why was Joker and the crew of the Normandy high-tailing it out of the battle BEFORE Shep made that 3-colour choice?
Why were some of the crew-mates on the Normandy when they had JUST been with me charging for the Conduit? They died or got seriously injured, didn't they?
So many unanswered questions. So much more unsaid - how did the galaxy recover without the Mass Relays? How did the massed fleets return to their homes? Etc... etc...
Please answer us and make an ending WORTHY of Mass Effect and Bioware.
Thank you
