We all know the clones. And often, we welcome them. After all, you can't play Blizzard's World of Warcraft on a phone, so Gameloft's Order and Chaos seems like it fills a hole and doesn't hurt anyone. Cloning isn't new, either. From Pong, probably the most copied game on the planet and allegedly a copy itself, to Breakout, success has always bred various degrees of imitation.
