Surprised there's not a topic on this already. But yeah, bout a week or so this came out on PSN and X-Box Live. It's more than just Super Street Fighter 2 Turbo with HD graphics though. When fighting you can either choose from the remixed fighting system or the classic fighting system that was used in the original SSF2T. You also have the ability to play online and from what I've played so far, the online is pretty good. For me so far most of my matches have been lagless except for in a couple of rare cases. Now, if you're a purist and want the original graphics, Capcom has included the option to switch between the original character sprites and the HD ones. You can also choose from the newly remixed soundtrack or the original SSF2T music.
Overall, for about $15 this is a pretty good deal. But yeah, I want to hear what other people think about it. And if anyone's on X-Box Live and wants to have a match, I'm up for it.
