I'm right there. Right at the end. I only have two more missions left to do, and then it's all done. I'll have finished the series.
I completed the Shore Leave DLC, which was hilarious and fun. I greatly enjoyed having Wrex back on my squad, it was like old times. He and Garrus were my two squad staples, I never wanted to bring anyone else with me. So that was fun to revisit, and all the dialogue! There were a lot of great bits in there. I wanted to save it for last, just before the end.
On the topic of the ending, I've spoiled it for myself. I know what the choices and the consequences are. I've been trying to decide what option to go with - right now I'm strongly leaning towards the "red" choice. It's terrible, but more in line with what I think Shepard has been working towards this entire time. Of course, I won't know what I'll finally decide until I get there.
But I don't want it to be done. I put off playing today. Maybe I'll play in a bit. I don't know. I just don't want it to be done yet.
