I am looking for a name of a genre. Or maybe not a genre but just a game mechanic that seems to have become the primary defining feature of many mobile games. Games of this kind are characterized by: - A battle phase - An upgrade phase - Many different currencies, upgrades, bonuses, cards, special items, etc. - Extremely easy and simple gameplay in the battle phase with partially (or entirely) automated controls. - Outcome of battles determined not by player skill, but by upgrades selected in the upgrade phase, and more importantly, on how much real-life money is spent. - Free to play with In-App-Purchases I can't actually remember the names of these games. I have just seen people play them. And I remember having downloaded such games, uninstalled them after ten minutes, and forgotten about them. The only game I remember the name of is "Mortal Kombat X" (for mobile), because it was based on an established popular console title. But to my great surprise they changed the genre from fighting game to this... other genre... I would call it "Endless Upgrader", but I am thinking it must have an official name. So what is this genre called anyway?
