Very much enjoyed Halo Wars, and would welcome a sequel. Yes, it was more limited than other games of the genre due to it being on console, but it was still a fun - streamlined - RTS. No less satisfying to build up a legion of troops and storm enemy bases. Heroic pushed you to manage your units quickly and effectively; and I can only imagine how much more demanding Legendary is. Those vehicles need to appear in the mainline games. Also interested from a story standpoint, too. Some cool characters, and important events, spawned from Wars. Bring it on, I say.
