There's been a slew of new "serious" games out recently, but one that I think is really interesting (not to mention fun) is McDonalds. The game, which blatently rips most of McDonald's most sacred trademarks, is one of the most effective yet scathing rebukes of fast food I've seen. This game is seriously disturbing on so many levels. There's an interview with the creator here.

Furthermore, since the game is licensed under CC and freely available in a barrage of formats, we can expect to see it disseminated pretty far and wide before McDonald's scares them off with a C&D or sues them out of business. Interestingly, the creator talks about this in the interview:

Why did you single out McDonald's as your subject, why not another fast food brand?

Simply because it's the biggest and the most well-known brand. We could also use a generic fictional brand but we thought this would weaken the relation with everyday life.

You said it, brother. Now I'm off to grab one of those new spicy chicken sandwiches at the local MickeyD's. :-)
