eldavojohn writes: Ars analyzes some knockoffs and near knockoffs in the gaming world that lead to problems with the developers. Jenova Chen, creator of Flower and flOw, talks about how he feels about the clones made of his games. Chen reveals his true feelings about the take down of Aquatica (a flOw knockoff), 'What bothers me the most is that because of my own overreaction, I might have created a lot of inconvenience to the creator of Aquatica and interrupted his game making. He is clearly talented, and certainly a fan of flOw. I hope he can continue creating video games, but with his own design.' The article also notes the apparent similarities between Zynga's Cafe World and Playfish's Restaurant City (the two most popular Facebook games). Is that cloning or theft? Should clones be welcomed or abhorred? Are the necessary or just the result of a lack of imagination?
