My hate for proprietary software started way before I heard the words
"proprietary/free/non-free/opensource software", when you start to see
applications crash, with licences everywhere, and you can't replace them,
this is when you start to think a little bit more about the "what's inside
the box" and that's (in my opinion) the moment when you switch to Gnu/Linux
and then to Only Free Distributions.
The problem with big applications and games, is that it requires a lot of
people working at full time, and most of the Free projects are... well...
Free as in Free Beer, and only donations don't allow the developers to work
at full time on such big applications, and because of that applications like
Blender, Gimp, Kdenlive start to have problems with continuing their projects
as they would love to (even if the first 2 are in a better financial state
that the last one).
As for games, if it's a 2D game then one person could do it (I am starting
that will be Free Software (but paid) and probably I will use Kickstarter to
promote that, but that's another question), but for 3D it is so much work
that, or you work with applications like Blender that can easily handle
everything, or you will have to work with more people in order to have
something working (without the guaranty of any revenue at all).
