In the summer, we like to take a break from all the serious open source applications that we usually cover and take a look at some apps that are just plain fun.
This year, we've updated our list of the "funnest" open source applications with more games than ever before. In fact, the 2011 list has 74 games in all, including 46 that we've never featured before. At the end, we've also included a few apps that aren't really games, but are still pretty fun.
Notably, the majority of the apps on this list run on multiple platforms, so you should be able to find plenty of games for your system, no matter which operating system you run.
If you'd like to call attention to a great open source game that isn't on our list, please make a note in the comments section below.
