Add Turn Based Strategy to the list which Nintendo owns with Fire Emblem and Advance Wars. I suppose one could make the case for Sega with Valkyria Chronicles. However, Fire Emblem sales on 3DS have been very good and way better than previous iterations.
RTS never made a huge impact on console gaming. Halo Wars is probably the best selling console RTS of last gen (considering there is basically no competition for RTS on home consoles). I enjoyed Battalion Wars 2 but it had its flaws.
