Space 4X sim Stellaris is to receive its next major overhaul in May this year, with changes to the pacing, presentation and systems affecting performance.
I’m not really familiar with Stellaris, but with EUIV you really don’t need all DLC. Basically the DLCs are fleshing out one faction. So you get some special features and events for the Ottoman Empire, Venice or China that enhances how they play. If you do not want to play as Ottoman Empire, buying the DLC is pointless. If you have several hundreds of hours played, buying a DLC gives you something new and an excuse to start the Venice playthrough. I assume that they are handling Stellaris similar
