End of Nations is something of an experiment. To my knowledge there’s never been a genuine MMO RTS before, so operating on the basis that this is something someone is going to pay a subscription for is kind of foolhardy, especially when it’s a completely untapped genre. That said, Trion Worlds claim that End of Nations will have completely free single player and co-operative campaigns, as well as around fifty multiplayer battles that people can participate in, in the game’s persistent world.
There are, of course, other options to pay for things if you’re so inclined, but they’re accompanied by phrases like “extra value and convenienceâ€, which can mean anything in legalese.
Thanks, RPS!
