Analysing GC/DC and Million Arthur Core Loop, Monetisation and their Comparison

Some time back I was reading this Game Analytics blog. It basically writes about how freemium games monetise. There is a core loop going on in these games that keeps the players coming back as well as time-based restriction that can keep player interested due to the constant short burst of playing time. GC/DC and Million Arthur was not discussed yet (closest card game analysed was Rage of Bahamut/Marvel: War of Heroes) so I will attempt to write about the core loop of those games as well as the way they monetise. For those interested, that blog has done Puzzle & Dragons. (I'll be focusing more on DC than GC actually)
