Woah now, Clash Royale is a good game that is skill driven.
People take level 1 accounts into legendary arena which shows that skill dominates money.
How on earth the devs at Supercell tricked management into making a skill rather than money based game is genuinely a mystery to me.
That I certainly agree. But I do think the future are Games built on top of Game engine. Unreal seems to have a massive improvement changelog every 6 months and if Unity didn't exist I did doubt how anyone is going to compete within a reasonable budget.
Game Engine Choices would become the old day of OpenGL vs DirectX. No one sane would write their own game from scratch.
The games that grow out of the app store ecosystem are games like Candy Crush, Clash of Clans, Clash Royale, etc. I'm not saying good games don't exist on the platform, I'm saying the platform is conducive to low quality games. Almost all of the great games on the app store did not grow out of the platform.
