I have a thread going at PPM, my mod is called Scorched Earth, and it doesn't require any patches or extenders of any kind, because it's for the core platform, with none of the YR nonsense. I've planned to finish the mod as stood before I crashed a hard drive, but with the improved tools, and improved knowledgebase, I've become slightly more ambitious for it 
I'm currently working on updating my old voxels, I have to replace a few buildings like the airbases, and I'm creating a bunch of new civilian structures for better urbanization. I already made a new city sized water tower, a cell tower and a number of buildings with damage and garrison frames. I also have started work on additional neutral military structures, like a mega bunker that can garrison a ton of troops.
Anyway my masterpiece is the AI, it's clever, it's devious, but it never feels like it's cheating as so many other mods/games do. It plays more like a real person, each house with it's preferred tactics. To put it simply, on a good map, you vs 3 brutal AI, even in free-for-all will be a serious challenge. I know all the units inside out and it still kicks my ass sometimes
I recommend playing against the AI on various maps, land and water based to get a feel for how units match up, the game is radically re-tuned, and stolen tech plays a bigger part than ever. I recommend starting against 2 AI if you're a pro, and work your way up... but I find 3 is the sweet spot when the game becomes a nail biter, when you both applaud and curse the game
Once I finish it, I hope you guys are willing to give it a thorough thrashing here. I've reworked the balance around every new unit added, moved units from house to house finding the best home and so on, but complex games might reveal minor imbalances I can fix.
If I ever do port the mod to the YR engine, probably with Ares, I'll have to de-yurify the whole game. To me YR feels like a cheap mod, like one of the million aborted projects by noobs, the art sucks, the gimmicks suck, very little of it appeals to me as a proper war game... /end rant
I hope I'll give RA2 stalwarts another reason to fall in love with it again
