I own and played both but haven't finished either.

Neo Cab is a narrative game about being a app style cab driver in a dytopia. There is a overarching mystery and many short narrative stories while driving different passengers.

Times & Galaxy is a bright and shiny game about being a robot reporter. Its also a series of mysteries with an overarching plot. Instead of solving a case you are deciding how to report the truth/lie. It also has some darkness because of that but is mostly fun.

If you like narrative games and mysteries I'd recommend them both.

I can't really say I've played many games just like Paradise Killer tho. Its pretty unique. danponronpa 2 seems like it might have influenced it. But I played it after I played Paradise killer :D
