Relic Entertainment is one of best long lasting game development studios with rich history of successful RTS franchises. Every gamer has at least heard about Homeworld, Company of Heroes and Dawn of War games. They had some tough years when their publishing company THQ went bankrupt. All that talent would go to waste if SEGA hadn't purchased their company. Dawn of War 3 is their first Dawn of War game under SEGA, and judging by the game review it is clearly a transition period for them. My strong guess is that the next game they will release will be something spectacular.
Here is the excellent Gamespot video about history of Relic, well worth the watch if you liked any of their games released over the years.
