A previous game implementation in D would be interesting and if 
you do it you are welcome to write your about experiences here. 
It's hard to say what features you would take advantage in D as I 
haven't seen the code in C/C++. However, one thing is clear D 
would be an easy port because it is so close to C/C++. Every 
algorithm can be ported directly without any bigger change. If it 
would Rust you would probably have to rethink some of the data 
structures and it would be more difficult. Another thing that is 
clear is that productivity would be high. With today's fast 
machines and old games you don't have to worry about any GC 
pauses as there is plenty of time for that. You can basically use 
the slow "scripting language" features of D. I would expect that 
D is in the C# ball park in productivity for such task.
