Don't let the GC prevent you from writing a game in D.  D is the 
most flexible language I have ever used; you just need to learn 
how to deal with the GC in your game.

Jonathan M. Davis gave you some good advice and explained the 
fundamental problem with the GC in real time games (the potential 
for pauses during reclamation).  You can avoid that in a number 
of ways like temporarily disabling the GC during the real-time 
part of your game, just to name one.  More can be found in the 
resources below.

automem (https://github.com/atilaneves/automem) also gives you 
reference counting in D (C++ style), if that will work better for 
your use case.
