What makes Clash of Clans a great game is the trademark Supercell winning formula approach to game development. First you take an existing social game theme. Then you benchmark and reverse engineer the best titles in that genre in order to create a strong and natural feeling core loop. You follow up by building a game around that solid core loop. Sprinkle a new and improved game play twist and dress it up in stunning graphics. Finally you polish the game to perfection with a limited beta launch by making the game available only in Canada. Once it’s polished and the KPIs look solid it’s time to come out with a bang and take app charts by storm.
But even though Clash of Clans is the best there is it’s still not the best there could be. Despite being extremely polished and reworked on the basis of the genre benchmarks Clash of Clans has plenty of room for improvements in some key game play mechanics as well as in the virality and even monetization features.
