Why another complex minigame that will probably die in 2 weeks?

My only issue with Mahjong is the time investment. If the cut the round time down to 5 or something it would make me more interested to play. I actually got the hang of it with the novice NPC, but after around round 4 it started to get tedious.

More seriously, the dev team should stop use their money, time and effort doing those things and do more new content, I would have preferred a second dungeon in this patch instead of a mini game that no one will play in a week.

Yoshi P directly refuted your claim. He said that Mahjong was a side project for the dev team during their downtime, and it uses a licensed mahjong engine to run the game. You would have gotten this or nothing. If you want other examples of this, look at 16bit titan, the FFXIV fighting game, and Alexander tactics on youtube, thats what the animation team does in their down time.
