So I was recommended Stellaris on Steam since it's similar to Spore: Galactic Adventures and it definitely sounds up my alley, but 13 DLCs is a bit overwhelming. X'D For the sake of not breaking my bank, which ones should I go for? Or should I stick to Vanilla for now?
"Hey, That's what Spore should have felt like in the Space Age" was actually my thought after the first few hours of playing Stellaris, so, the recommendation is sound.
As people said, vanilla is fine.
If you want DLC, I'd say Utopia and Distant Stars are the two that were the most fun. One adds hive minds and "classic" mega-structures the other enriches the game's events and storylines.
As for 2.2 being bugged, the biggest issues right now are that the AI isn't very good at handling the new game systems (still plenty of challenge for your first game) and that Synthetic Dawn content (robot empires) aren't really well balanced for the new system.
That said, 2.2 is playable, and without a pre-conception of what a Stellaris game ought to be like you may even like it more than the older versions.
