Mobile gaming boomed years ago as the devices got more powerful but people ran away from paying for good content and demanded free games because "its mobile", which in turn led to the entire F2P/IAP culture developers now embrace. I loathe IAP/F2P and gladly paid £10-15 for good games on mobile, which are now extremely rare.
I went back to console gaming two years ago and the stuff you see releasing on mobile now, the odd gem aside, is utter dross.
My iPad has:
F1 2016
Monster Hunter
The World Ends With You
AG Drive
All the GTA's
Strangers Wrath
Munche's Oddysee
Real games. Premium games for a premium device. Add to that the amount of games I paid for but lost due to lazy developers not updating for one version ahead of iOS; 2K and BioShock and SEGA with Jet Set Radio being the main two that grate.
