Planetary Annihilation: TITANS, the massive scale RTS now being continued by the new Planetary Annihilation Inc had another small patch recently to further improve it.
After the recent update to add in more multi-threading, they've expanded it a step further. Released on Friday last week, update 112314 added in experimental multi-threading on official servers, performance and memory usage improvements to navigation cost cells, more logging so they can find issues, plenty of AI improvements, some server bugs have been fixed along with modding adjustments and making orbital attack lines in the orbital path visualiser more visible.
I'm really quite impressed how quickly they've come back to continue improving this RTS. They've got a lot more improvements to come, as they haven't upgraded the software behind various parts of the game yet like the UI system and so on.
It's quite different to any other strategy game, especially since the maps are based across entire planets you scroll around. I love the fact that the mini-map is essentially another game window which you can set to watch any point you want, it's very cleverly done.
