What games offer multiplayer between Microsoft's platforms (Windows Phone, Xbox 360, and Windows 8 or RT). This is what we have so far:

Skulls of the Shogun: Xbox, Windows Phone, Windows 8/RT
Galactic Reign: Windows Phone, Windows 8/RT
Wordament: Windows Phone, Windows 8/RT

That is the only one that comes to mind in the way you are thinking. You can play wordament cross platform.

Galactic Reign is another game no? It's on Win8 and WP7/8

Thanks. I'll keep adding info to the original post as it comes in.

my dice game for example :) not the AAA title, but multiplayer between Windows 8/RT, windows phone and web SL clients works fine. I'm planning to add more platforms if i will have time some day.

Also I played ARMED! on both WP and Wiin8, don't remember if it has cross-platform multiplayer - need to check.
