I am developing a 2D, multiplayer, persistent, online real time strategy game. I am using C# and DarkGDK.Net. I don't have an official name but my working title is RTSWO (real time strategy world online).
Most RTS games are military based but mine is going to be business based. It will be about earning money, paying employees, buying and building assets, resource collection, goods production, etc. Combat is definately a route to earn money but not the only way. My initial theme is future/space/sci-fi based but it should be flexible enough to accomadate any theme.
The download site is
http://www.projectrts.com. It is a very basic site but it has all the links required to run the game.
I have a development blog at

Currently I am using the free RTS images from the abandoned game called Hard Vacuum I found at lostgarden.com.
