This will be a short rant because I am drunk and incoherent. Osamu edit this in the morning.
It’s extremely often I read about discussions of various mahjong clients/software, and someone will come out of nowhere and say “but it doesn’t have ________!”
As a normal player who has never even considered programming a mahjong client or software in my life, I am as harsh a critic as any, perhaps even more so than the various people still playing single hand rounds for money on mahjongtime. But people whining because the client of your choice does not allow you to open riichi/ron on concealed kan for kokushi/insert annoying variant here never fails to annoy me.
