It looks like they're adding the Commodore 64... apparently, it's been available in Europe for almost a year. I was pretty much raised on the C64, so I still enjoy playing some of these games, mostly just for nostalgic value, though. Unless you had one a while ago, I wouldn't get real excited about any of the games, except maybe Space Taxi. But it's not even available in Europe yet. And the Impossible Mission games were pretty cool. And Jumpman. I didn't play some of the available games, so they might be great, too.
Here's the list of games that have been released in Europe so far:
