What's the hottest PC game out right now? Judging by the sales numbers World of Warcraft is still way ahead of the pack. Now, from a publishers perspective the best thing to do is to try and copy the game, hoping for an equally successful title to be made. The problem is, the market is kind of saturated right now, so not only is it hard to penetrate the market, it's near impossible to make a title that is different enough from the rest yet at the same time generic enough to fit all tastes. A possible solution? Instead of copying WoW have a look at Blizzards back catalogue and do your best to mimic one of the games on the list. If it worked out for Titan Quest it sure as hell can for a game that has zombies with cannons sticking out from their abdomen!
