Wow, William & Sly is freakin' addictive! I'll definitely be playing that again in the near future. :) Run Around the World is also great!
Also, this is totally off topic, but I sent you a PM about two weeks ago regarding putting medals in games. You haven't replied yet, so I'm assuming you either haven't gotten a chance to look at it, or that it somehow didn't make its way to your inbox. So if you could give it a look (if you received it) when you're not busy with anything, I'd really appreciate that!
