Hey hey! Telltale Texas Hold'em works (although the Launch Game button didn't show up in the wrapper, I had to click where it was supposed to be). I'll try some of the Sam & Max games.
The free trial is only 7 days.
EDIT: No luck with Strong Bad. The icon appears in my dock but the game never launches, and after a while the icon just goes away.
EDIT2: Sam & Max 205 works, but it's kind of laggy, even with the graphics quality set to low. Then again, I'm using a low-spec MacBook with integrated graphics, so that's probably to be expected.
All in all, it's a neat trick! I hope some Mac users out there are able to play the games this way.
