I love this card game called Summoner Wars. It’s kinda like a simplified version of chess where you have to pick up a faction (lots of different decks to choose) and the goal is to defeat the other player’s summoner (think like the king piece).

My NT gf loves playing it despite not being into board games. It might take a couple of hours to get used to the rules, but they’re very straightforward and have minor changes depending on which faction you choose to play.
