I am not absolutely sure if it's ok to post about my own project, but since here seems to be people with similiar interests...
Focus of Armored Brigade is in combined arms warfare. It has two settings, WW2 and Cold War. Maybe the best description would be something between Steel Panthers and Close Combat. I think this is quite unique game/simulation in today's offering.
The game is still in development, first release is probably in early 2008. Current graphics are temporary and so far completely done by me but when I get my artist working things should start looking prettier.
And best of all, it is 100% free! Yes, no commercials, no demos, no spyware.
