It's better to discover the scaling problems of the D GC with an open source video game than with a commercial project. And currently Minecraft is hotter than Doom, so it probably gives better return of investment regarding number of persons that will be interested. So I agree that a Dinecraft is a bit better idea.

But today it's not hard to translate Java-OracleVM programs to D and find that once compiled with DMD they are are slower than before (to avoid this you need to care for performance). I suggest to perform a 1:1 port of the Java code, write tests, benchmark and profile the program, fork the code to keep a working and clean root version, and then slowly optimize the derived version keeping the tests "green".
