Well, that depends how comfortable you are thinking in terms of machine code. It takes a completely different mindset because you're now literally dealing with blocks of memory -- even more so than C. It also depends how steep of a learning curve you want to encounter. I, personally, have not yet played with x86 assembly because the documentation for them is so unfriendly for beginners. To that end, when I want to play around in Assembly and learn techniques for that level of programming, I usually play with the DCPU (http://dcpu.com/dcpu-16/ http://dcpu.com/dcpu-16/). It's fake and was designed for a (sadly) not-to-be-made game. But it is an absolute joy to program in. Play around with that until you're comfortable and THEN tackle x86.
