All new copies of the game will come with those maps for free. I just always see people complaining because maps aren't free. We could go back to the old system of no new maps ever. (aka wait until the next game)
Peter Molyneux doesn't make games that people want to play on a PC. Massive Multiplayer is the main lure of PC gaming that consoles don't tap nearly as well. Age of Conan is going to really take off also.
It's a good game, but had some problems. As they continue to make fixes it just gets better and better. This game actually takes advantage of dx10, dynamic lighting and weather are especially nice.
