just finished it. but i chose the left hand option.
i saw the other endings on youtube and they are all the same with different colours. i am also dissapointed in the endings. could have been so much more awesome, emotional, powerful like the main game storytellling is
hate the way it dumps u back onto the normandy with an earlier save point to allow continuation of playing too. doesnt feel right. should have also had a bit on the ending where the council use the lazaras project on you again.
I do hope bioware continue the ME story/universe though one way or another. i found it gripping. they should do what bethesda did, create a new engine and continue the series. the engine was looking quite poor in a lot of areas.
