It's been a long while since I last posted, due to senior trip and other things coming up, but development of this game is still alive and fresh. Sadly, I must part ways with 3D Gamestudio, as it's scripting system was just a little too buggy for me (It's move functions failed miserably). I'll be using the engine in the future, but not for an RTS game.
I've switched over to the Spring engine, which is much more easier to use and has an active community. I'll have to learn some Lua to program the Turn-based portion, but it'll all work out. I've mapped it out in my head, using the limitations of this new engine, and searched for a couple of workarounds.
So far, development on this engine is successful, and the first tank model had been successfully imported. So it's safe to say that the switch is official, and Spring will now be used.
