Visa gets you in the games

Ok, so this post's headline sounds a little like I work for Visa. I don't, well I used to... oh nevermind. If you've been on the NBC Olympics site, you might have noticed the online games you can play on the Visa sponsored game area. Find it here: Visa Games

I'm not usually a fan of Wild Tangent but I have to admit, they must feel bigtime when they're making an advergame for Visa as part of the Olympics. Doesn't look half bad either but I don't know if I'm convinced it's worth it. Someone show me some ROI data. You do have ROI data don't you?
