Beyond Protocol Went offline
Gods and Idols is currently offline
and now Boundless Planet is offline =(

I know I've made this post a year or so ago, but I am making it again. If you have a MMORTS you currently play, please post the name so we may slaughter each other horrendously on the battlefield. The only other MMORTS I can think of is Mankind, but I am not yet willing to pay money each month for a buggy game with a player base of 5..

Try: www.afterprotocol.com
The full source code to Beyond Protocol was released ages ago, there are numerous forked projects of it.
Never played it though, so no idea if they're any good.

Also, Gods and Idols isn't ''offline'', it's ''in development'' ;)

Played After Protocol all the time 2 years ago. It's tons of fun but the player base was very very small. I'll try it again and see how it is.
