Well maybe its time for an upgrade. The potential that this game has when it comes to fighting in general is amazing. The idea its based around isn't entirely cutting edge and new but the take on said idea is like no other game I have ever played. If they play their cards right it could very well become the next big thing. I know that the main reason that we are being held back in development is, for starters the whole team is comprised of unpaid volunteers who, although devoted to the game, are not entirely "bound" to it, next is because since this game is "free to play" money is not on a constant flow as is with other games. If anything as big as an engine update were to be brought about it would likely be due to a change in the way funds are gained.
