I'm using the game programming language Blitz Basic 3D (Blitz3d), since I've always been more familiar with Basic than C, and it seems to run well enough with my creations.
The game is still in early stages, though I've got a working 3D tiled map editor for placement of terrain, strutures and units. Anyhow, feel free to check out my game-in-development website at:

Feel free to tell me what you think, here on GameDev.Net, and I'd love to hear suggestions from people who are interested in playing Mecha themed games as to features they would love a turn based mecha strategy game to have. I might even implement such good ideas into my finished product :)
I gave you a rating++ because it is your first journal entry, but mostly because I like what you're doing with this game. I look forward to reading more in the future.
