Slitherine

I've been a wargamer since the old Avalon Hill days (started with Tactics II). Now I am a Big Brother to a 10-year-old Navajo boy. He's a great kid, but has some issues. Until I took him to see Hacksaw Ridge, he had no idea World War 2 even existed, but now he's developing an interest. So I need a game I can play with him - not too complicated for a beginner. Battle Academy & Heroes of Normandie are only 1 player. Any suggestions?
Thanks.

Panzer Corps has a offline hotseat mode.

Heroes of Normandie and Battle Academy can also be played as hotseat but you need to be connected online.

BA & HoN are both fully multiplayer games so you can play them!
