I can't say much about the community there, but not knowing anything about them I'd give them the benefit of the doubt and assume they are just amateurs who love video games like myself and are trying to learn enough to make their own. Whether or not it's to try to cash in on the indie craze or to produce something for yourself, I can't say for them. For me it's the latter, and if it one day leads to making money, great! But first and foremost I'd like to scratch the itch to just make something cool. I have some actual bonafide education with 3D modeling and animation, but my coding skills are very basic (some shell scripting as a Unix admin, some javascript, a little bit of this and that to do small tasks) but I'd like to learn more C# or C++ and work on making a board-game like game I've been thinking about. My hunch is that the Unity crashes might be related to my old video card or it's drivers, I'll have to try it out again when I can or after I do an upgrade. I full accept my status as a wannabe/amateur/beginner but you gotta start somewhere, right? That said, for the people trying to actually market their stuff on Steam (for example), I am seeing a lot of pretty uninspired stuff. I am astonished to find choose your own adventure text games on there (for sale!). XBLIG was a little bit the same, with cool titles like Protect me Knight (admittedly done by professionals) alongside "Try not to fart." So many wreaked of school projects, which like I state above, learning how to make things with these tools is totally acceptable. Charging money for some of the results is pretty laughable though.
