Haha so many questions. Its all on the website and whitepaper to be honest but in short for you.
Chimaera will use its own custom blockchain so that it can support one of our very unique features which is hosting complete decentralised game universes.
Chimaera is not only a game development platform but also a gaming platform. Since developers can create these games entirely on the blockchain everything that you own in the game will be truly yours and so we will also offer a platform where you can trade these ingame items, accounts, coins or whatever you like.
Maybe its nice to check this video... Its really awesome ;-) https://www.youtube.com/watch?v=O0s-5L3_oE0
