Hi Savagesoft,
yeah, I would like to do a RTS sample game, but I have not enough time right now. You can come back to the current game project I'm doing in 1-2 months and ask more questions there (
www.ArenaWars.net) if you like more information about RTS games. There I would be happy to discuss techniques important for RTS games and hopefully I got more time then for discussions like this ^^
BTW: My initial idea was to build an RTS starter kit for XNA, but a racing game made more sense for the Xbox 360 and an RTS starter kit would probably have been a lot more work, so I'm glad it "just" was a Racing Game :)
