I dunno. I was using 1.0 before, but I had both. Whenever I get a computer again, I'll probably have both again. I was going to use 1.1 for a marvel game because I didn't feel like recoding EVERY character and stage I had. I wanted to do just a select group. Overall, I like 1.0 for my stuff because it IS low-res, but for high-res, I might opt for 1.1.
