that would be amazing but i don'T think it will ever happen, (At least never with new releases) because the producers of the games would probably have to cooperate and i'M sure those companies hate gamefly.
Gamefly likes to maintain a certain number of games in their inventory, for example they might like to have 1000 copies of Blitz 2 in circulation when it launched. once interest in the game waned the lowered the price of used games and sold them off without replacing them until they only needed 100 copies to keep up with demand.
They aren't selling Blitz 2 because they need to keep X amount of copies so they can rent them out.
With such a low level cap and questionable endgame content you might be able to "beat" the game as both hero and villain in 3-6 months. They seem to be promising expansions and the like but i think this MMO has a rather short life expectancy.
