I want to say wait for Phantom Liberty just because I hate replaying myself a lot, but if you can’t wait the game is in an excellent shape. It’s not the most deep RPG I’ve played, but if you like cyberpunk settings then Night City has you covered. The game also has some great quests and characters.

So if you are comfortable with replaying with Phantom Liberty, then go for it champ and get it now. But if you only think you have the stamina for one playthrough, the game can be quite long if you are a completionist playing the side quests and gigs, then I suggest waiting for Phantom Liberty.
