Switching gears a little bit from the bloody GTA mentioned above, is a game that truly anyone and everyone can 100% enjoy. It's an action game in a way because it gets your heart going and is extremely exciting.
Alto's Adventure was released in iOS in 2016 and later came to Android. Instantly winning awards and jumping to the top of download charts. It's extremely fun, addicting, yet casual at the same time. It's hard to explain, but just know that it needs to be on this list.
Oh, and the developers are working on a sequel called Alto's Odyssey coming this summer, so you might as well finish this one in the meantime.
