Yes, we started this list with Minecraft Pocket Edition. Everyone knows it exists, and many Minecraft purists probably think it's not as great as the PC version. But we're talking about quality mobile games.
Imagine we're in a parallel universe where Minecraft is only available on Android and iOS devices. This game is actually pretty feature packed for a mobile game! It would be a disservice not to take this game for its own merits apart from its PC big brother.
Minecraft Pocket Edition was picked because not only is it a classic example of a real building/survival game on a smartphone, but it also takes concentration, mastery, and knowledge of Minecraft to play.
