To start off, I'll note that I did not fail to see the helpful wiki on development apps. I'm currently downloading the OSX Subversion client as I write. Problem description: Brother and I, both currently working on a CS degree, want to write a little game with our free summer hours. Because we have different blocks of free time, we won't be working on the code at the same time and place. This is especially true if the project carries over into the school year. But research into the topic is losing me in a sea of corporate level applications Is there (and perhaps subversion is the answer) a brain dead simple easy to use source control application out there that would help us: A: Track files changed B: What those changes are (in a comparison manner). C: Free/Opensource Also, we are (shamefully) doing the initial dev work in XP using VS2005. We want our app to be cross platform and we are more familiar with VS. Since many of you Moon Light as developers for "the other" platform (whichever that may be) can anyone answer the question above, but for a windows based app? Thanks everyone! ~Tyler (side note) I use Perforce and BeyondCompare at work. However, I'm teaching my younger brother a bit (advanced VS use and C#), and we are both going to have to learn the XCode IDE. I don't want to add another complicated source control program to the mix. However if need be, I could learn it.
