I don't like putting pressure on the analogs and using them at the same time, what's so bad about holding A anyway, with the TYPE A layout your thumb is doing nothing otherwise.

I didn't mind the inventory too much, got used to it quite fast ( played the demo too much :x), but the thing that annoyed me like immensely, is that your armor takes up inventory space..... I mean what? Why not let the rest of your clothes take up space as well... rediculous.
Yathzee said it best, "you are carrying armor in the pocket of your armor"...lol.
