I on't get to play PC games as much as i'd like.

I played World of Warships for a while and its enjoyable but each game just went for too long.
Now I just play Europa Universalis 4 if I'm on PC. so much time can disappear on this game once you know what you are doing.

Mostly i play mobile games on an iPad.

PubG mobile
&
World of Tanks Blitz

If I have no mobile reception then FM mobile definitely kills the time.

Both incredible games for a mobile platform.
