StarCraft is too hard to play with friends and StarCraft 2 made the wrong things easy making the big army fights take 2 seconds.
Magic the gathering not only has power creep but rules and mechanics creep making the game even more complex over time. Also the focus on printing cards specifically for EDH/commander makes the format less interesting.
Pokemon TCG none of the meta decks use guys i like and it's because the ones i like all suck.
DotA and mobas are basically entirely suffering and the games are often prolonged by people who enjoy suffering.
