In the world of MMORPGs, the same formula in games made has been rehashed and repackaged over and over again. There have been basically no "mind blowing" new gameplay features added to any of the recently released games that have changed the gaming industry. However, game developers already know this and have put a lot of effort in providing new packages, in this case gimmicks, to the same old gameplay system found in every other MMORPG. You can smell trouble for a game if it has in one way or another failed to make its own mark on a now jaded gaming population.
