This is the all time lowest price for this edition of the game on the Playstation Store.
From the website:
The universe is getting bigger every day! Paradox Development Studio is bringing the grand strategy genre to consoles for the first time ever with Stellaris: Console Edition. Featuring the same deep strategic gameplay, rich and diverse alien races and emergent storytelling, Stellaris: Console Edition puts the complexity of the galaxy at your thumbsticks. Whether you’re exploring the unknown, discovering the mysteries of the universe, or conquering it for the glory of your empire, console players have more inter-galactic strategy awaiting them than ever before.
Stellaris: Console Edition Deluxe also includes the Plantoids Species Pack, Leviathans Story Pack, and the Utopia Expansion for the explorer ready to take on even more in their adventure.
Enjoy!
I wouldn't play this game without mods. It's like watching paint dry in space.
