Online Game: Transcendent Peak

What is it like for someone with a collector's obsession and OCD to play a game?

In real life:

“Little sis, how many outfits from this collection are you still missing?”

“Have you tried every hot pot in this series?”

“Have you watched all the movies in this series?”

In the game:

“How many achievements are there in total?”

“Which set is the hardest to collect?”

“Have you heard of gear upgraded to +20?”

“What's the strongest five-star set you've ever seen?”
