Probably the best way to be confident about that is to switch to a 4:3 ration window and look at how much less stuff there is on the title screen to the right and left of the logo.

I'd take a screenshot, but apparently that's not possible. Which puzzles me a bit because Steam supposedly supports screenshots. Perhaps windowed games aren't included, but even the native screenshot utility is failing.

So, just wanted to say, Sonic CD is exactly what I'd hoped for. I couldn't be happier with it.

Also, while I'm not into tattoos, I just found this, and thought it was the coolest tattoo I have ever seen. If I was forced at gunpoint to get a tattoo, that's what it would look like :)
