I beat Mass Effect 3 on Sunday... And I will have to say... I am on the bandwagon... THAT WAS THE WORST ENDING EVER! Such an amazing story up til then. I chose the paragon ending... but I am sure the Renegade ending isnt much better.I will find out on my second playthrough. Once I complete my Femshep renegade char in ME2.
But until then... I stick to "Worst Game Ending Ever!"
