Even though there’s a drop shadow on the units, I’m pretty sure I can do this completely in 2D (not 3D). Also, I would like some animation for the arrows. But, again, I think that’s just 2D.
It should be fine. Just remember that native DLLs only work for the platform they were compiled for, so your windows native DLLs wont work on say Linux (if cross platform is a concern for you).
There was a time I had to do Atari ST, Amiga, C64, Apple //e, Apple IIGS, Macintosh, and MSDOS ports. Not any more. I just want this Windows version finished!
