Indie developer Nimblebit dropped a PR bomb on Zynga yesterday
 with it’s letter addressing the similarities between their hit iPhone 
game Tiny Tower and Zynga’s upcoming release, Dream Heights. This 
galvanized the gaming community, with thousands of people, from prominent bloggers to gamers on Reddit criticizing the company.
 
However, just after the new year, Atari ordered the removal of Black Powder Media’s Vector Tanks, a game strongly inspired by Atari’s Battlezone.
 This galvanized the community in a similar way, except this time, 
gamers were furious that Atari shut down an indie game company that made
 an extremely similar game.
 
Unfortunately, the line between inspiration and copying is incredibly
 blurry at best. The one thing that’s certain is that copying is here to
 stay. Copying has been present in some form since the dawn of capitalism
 (if you need proof, just go to the toothpaste isle of your local 
supermarket). The game industry is no stranger to this trend: game 
companies have been copying each other for years. Given it’s repeated 
success, there’s little reason to think that this practice will stop. 
Indie flash game studio XGEN Studios posted a response to Nimblebit, 
showing that their hit games were also copied:
 

 
Some would even argue that the incredibly successful iOS game Angry Birds was a copy of the popular Armor Games flash game, Crush the Castle, but then Crush the Castle was inspired by others that game before it. Social games even borrow many of their game mechanics from slot machines
 to increase retention. So what is copying, or more importantly, which 
parts of it are moral and immoral? Everyone seems to have a different 
answer, but it’s safe to say that people always copy the most successful
 ideas. The one thing that those in the Zynga-Nimblebit conversation 
seems to have overlooked is that everyone copies others in some way.
 

 
 
 
Of course, while imitation may be the sincerest form of flattery,
 it doesn’t feel good to be imitated when a competitor comes after your 
users. In this case, people may question Zynga’s authenticity and make a
 distinction between inspiration and outright duplication. But at the 
same time, Zynga’s continued success with the “watch, then replicate”
 model shows that marketing, analytics, and operations can improve on an
 existing game concept. Or just give them the firepower to beat out the 
original game, depending on how you look at it.
