Forgive them for what? They've done nothing wrong. It's their IP,they are to handle it however they choose. They don't need to apologize if the audience finds fault over something petty. Dragon Age 2 has the same issues that Mass Effect 2 had: Oversimplifacation. And,although it's a bad thing,it did make gameplay faster and feel more fun,so the negative impact of the oversimplifacation is easily counterbalanced by the new fun that was added. And the Mass Effect 3 endings...First of all,let me put on my flame retardant suit.
Now,the ME3 endings were meant to end Commander Shepard's story. Either by going MIA,KIA or simply retiring,this was the end for him. How BioWare decided to tell that ending was their choice,and given the circumstances of the game,made sense and didn't warrant the borderline psychopathic response that it got from the playerbase.
So,I'll say it again. Forgive them for what? I have nothing to forgive them for. The only way to improve is to change,and there will always be people there to protest change. Just relax,and when Dragon Age 3 comes out,play it and love it,and if they decide to release a new game in the Mass Effect universe,I know I'd play it. Maybe it'll be about the Morning War or the Relay 314 Incident. Or,hell,maybe it'll be an MMO. Who knows.
Besides,the whole Retake Mass Effect disaster will only serve,in the long run,to make the gaming community look worse. They don't need forgiveness,because,so far,they didn't do anything wrong. Well...Maybe except for forcing me to watch Gorion die. But I've forgiven them for that long ago.
