The World Ends with You hits home in my case: I used to seclude myself up
The game is about life&death, but the setting is a character itself. Shibuya feels alive in this game. People walking in the streets feel real. What is happening is as important as who are happening during the game's plot.
The music feels like coming from the streets rather than an MP3. And the gameplay is between a hack&slash, bullet hell and deck building.
Farming & grinding is funny too. And the game's mechanics can be easy to pick up and have a lot of depth at the same time.
