This Unity thing looks so awesome that I have no idea why have I never heard about it. At the moment I'm more interested in learning C++, but someday I'll probably take a look at it.

Well Obi, it's not as much about different strategies as it is about GM not being Construct. We can't use both, therefore yes, only one of us can program. I use GM for approximately 5 years, so I think I'll do fine if you leave it to me. Also, I have nearly no personal life, which is quite useful.
