Triple Triad is the same thing as Atma

[Kosmos992k]

basically you keep doing the same thing over and over and hope that the item you want will drop after 2-3 hours.

why there are so many content in this game that is so painful to play?

always the same thing with boring RNG. Atma, CT/ST/WoD, Triple Triad, Lottery, all different content but designed by the same concept.

Triple Triad is fun but playing with the same NPC for 50+ matches is not fun, and they use the same set of cards in every matches.

people are enjoying it right now, they'll play it for 2-3 days before realize that it's boring.

I'm not entirely sure that it's meant to be played with such intensity over a short period of time in order to farm cards, I think the intention was for it to be an aside to the main game that people can pick up and put down as they go. Honestly if people play 50+ matches against 1 NPC every day for 2-3 days and get bored, it serves them bloody well right.

PS. one definition of insanity is to do the same thing over and over and expect a different result...at which point I would refer you to your 1st sentence.
