Not being objective, but wouldn't CoM come after days? I mean, com takes places literally exactly as kh ends. Plus days ends and begins kh 2. Please correct me if I'm wrong.
I recently completed my playthrough of 2fm on critical and I have to say: it's not that hard. It was the second time playing the game, and I died less than on standerd. First off, it gives a lot of kickass abilities at the beginning. I actually found proud mode to be harder than this mode....
I asked that question because roxas and ventus were and are my favorite characters( most likely due to the fact that I played days and recoded first) and I had always wondered why in 358 1/2 days why Axel never slipped and called Roxas ven. Then I wondered would Lea call Ben roxas in 3. I just hope that in the end, roxas somehow comes back and makes lea feel bad about making the same friend twice.
