I rather enjoy Mahjong - the actual game, played in person even - and so it's a continuing mild disappointment that so often when a thing says "Mahjong" it's actually just tile matching, or a porn game, or in some cases both.

I played a decent video game rendition of the actual Mayjong - not tile matching, nobody gets their tits out, it matters whether you're actually any good at it - in the 1980s but I had no idea this wasn't a common thing, so I don't even remember the name of the software.
