Riichi is a good candidate for a video game due to all the specific rules. It has a lot of room for QoL. I have an app on my phone [1] that has made it fun to play and learn thanks to the guidance it has with the rules
Well the other options are the gooner gacha games like Mahjong Soul and Riichi City lol
Personally I play on Mahjong Soul because apart from Tenhou that has the most populated PvP with enough players in each rank + it's a butter smooth experience with all the small features. And I love the special modes like Battle of Asura
