The folks at Trion have released this video which introduces you to the three factions of their MMO RTS, End of Nations. I've seen the game at the last two E3's and have been fairly impressed with what the folks at Trion are doing as they've managed to make a RTS that plays well at both the large and small scale battles and has enough depth to keep people interested over the long haul. If you're an RTS fan I'd keep an eye out for their beta program which should open up later this year as the game looks very solid so far.
