There was a few problems I had besides the ending.
The entire arc of 2 was a problem. When you can pick your back ground and history in 1, I picked Sole Survivor.
Later in the game you find out Cerberus is the reason your friends all died in Sole Survivor. After that I went out of my way to fukk over Cerberus. Every single choice I went against them, blew up their bases, killed their scientists, etc.
Then in 2 you gotta work with them no matter what, and Shepard doesn't even mention anything from Sole Survivor, nor do they mention Shepard ruined all their shyt in 1.
The Rachni was another
moment. I saved them in 1, then in 2 if you choose to communicate with them they send a message that says they got your back if the Reapers attack.
They're in 3 no matter what you did in 1, and they're against you no matter what they said in 2.
Then there is several....probably 15-20 different choices that got turned into emails from 1 to 2. It's been years since I played the series but the "choose which colony to save" and "talk the girl out of suicide" are two that I
when they just sent me a message like "thanks breh".
Let me stop though because the more I think about it the more disappointed I get. 2 is still one of my favorite games of all time.
