Wow. Awesome. It's going to take me a little bit of work to adapt my conception of what a web browser is to imagine myself playing those kinds of games on it. Sounds dumb, but I think of browser environments as "open," and large-scale games environments as "closed." I guess the closest demonstration of what I mean is that I use a browser to do multiple things simultaneously and often run other applications along with it, but with hardcore games I shut down everything else on the computer and focus purely on that.
Speaking of which, I may have trouble using Chrome to play high-end games if I don't shut down 70 or 80 tabs...
