Well that rules out pretty much every video game. So here's my favorite card game instead.

It's called Illimat. It's very strategic but easy to finish a game in under an hour. It's essentially a game of pattern recognition and "harvesting" sets of cards. The goal is to harvest the most points each round.

Fitting into the overall theme of farming, there are four fields to harvest from, and each field is in a different season. Players can change the seasons by playing special cards, and the seasons affect the types of actions that may be performed in each field.

Everyone I've played with has enjoyed this game.
