My main problem besides of the ending was the gameplay. I mean it didn't felt like an RPG. In an RPG it's at least important to choose the right combination of followers, equidment and abilitiy but ME3 is just a 3rd person shooter where all this doesn't matters. I've always choosed the same weapons, the same abilitys and the same squad (Vega and Kaidan) when it was possible. Srsly Skyrim has more strategic deep than ME3 and I usually slay everything with my sword without overthinking it. Also the emotional part came too short. And Liara was always my least favourite character but it's cleary to see that Bioware has made her the canon romance option. I was also unable to gay romance Kaidan because of an bug.
