I have never been a big fan of RTS games. I enjoyed Warcraft II and III, but C&C, Starcraft and Total Annihilation never turned me on. There was one RTS that caught my attention outside the RPG genre. It was Star Wars: Battlegrounds. It was fairly balanced and sucked this big geek into the giant world of Star Wars.
Recently, I heard there was another Star Wars RTS in development. After SW:Battlegrounds, I have been anxiously awaiting the new Star Wars RTS. It may not be out yet, but you can check out a single map demo available for download from FileCloud.
