Mass Effect's insanity mode should have been named bullet sponge mode. All they did was add shed loads to every enemies' health and damage resistance, and make all of the organic enemies spam immunity.

That's it, 1050/1050 achievements, all difficulties completed, all paths viewed, and all three main classes used. It only took me 5 playthroughs, or 83 hours. Bring on Mass Effect 2.

I haven't chosen what to play next. No particular preference, so long as it's not Mass Effect!
