Agreed. Everything is blue, everything is mysterious. I prefer the time when we knew nothing about the Protheans except that they built cities from stone. And Reapers were a real threat instead of elaborate, brainless mooks you could take down in a few seconds.
ME1 is definitely my favorite of the three, though the combat is annoying.
Yep the story and sense of mystery is wonderful in 1. I prefer the combat and relationships from 2/3 though. I'd forgotten how establishing a relationship with someone was basically 'go be nice to them after every mission'.

I suppose it was like that in others too but it comes across as far more systematic in 1.
Am having issues taking cover in 1 but suppose that's because I didn't do it much in my first playthrough and have got used to the slightly different way of doing it for 2 and 3.
This is the first time I've persevered with a male Shep though. Its absolutely incredible the lack of depth I find the malesheps voice acting! I don't know if he's particularly bad or Jennifer Hale is particularly good but having the 'I'm attracted to you' conversation with Liara was painful to listen to at times...
