E:RT 2
Was going to attempt this concept, but unfortunately they didn't have the money, programming talent, and funtioning game engine to pull this off.
E:RT multiplayer game engine never worked in the first place, so that was pretty much the end of that.

last year, there's not very much demand for modern sub games in the open market (something along those lines). Meaning the time and treasure you sink into developing the game, you're not going to get the monetary return to make it worthwhile.
