Overall, exploring Stellaris game is not only worth it, but it's also a must if you're into 4X strategy and overly-lengthy gameplay which doesn't ever stop changing and producing numerous captivating experiences. It's a game that takes ages to master, but every single minute brings unprecedented quality gameplay.

The best damn space strategy game I ever played - only way to make it better would be to make the space area 3D, as is real space. That would awesomely change strategy, tactics, expansion, everything. But I'll keep playing regardless. 350+ hours so far. The DLC's are awesome too.

I jumped in on stellaris quite early in its lifespan. It never really grabbed me, and I bounced off after 'only' 80 or so hours.

It's quite... dull? Repetitive. You never feel connected to anything you do, the combat is nonexistant.
The main selling points, the exploration and dynamic races just feel empty.

All in all, it comes out to an empty game. Fill with DLC to your hearts content, but that is not a business model I want to support.
