Every change is a potentially breaking change, even if all the 
change does is fix a bug (your code could rely on the bug). This 
happens to me quite a lot with subtle things. Forever, 2.060 
revealed that I had overloaded the same function twice with the 
same arguments and same template constraints. Up till 2.060 it 
wasn't flagged as an error and worked fine. Yeah, it's my fault 
entirely, but it's something I had to fix.

I can't remember upgrading my DMD without having to change 
*something*, and my project is only about 10kloc, so it's not 
big, and I don't think bearophile is exaggerating at all.


To answer the original question: yes, D is more than capable of 
writing games for the major desktop platforms right now, even if 
things are a little unstable at the moment.

One thing I will say to you though is that you'll have to avoid 
allocations during runtime if you want smooth gameplay as the GC 
is quite slow, but you should be doing that in any language.
