I am planning to go for Xbox (actually, I am waiting for Pro version, the activision case brought up that there was plan for PS5 pro soon, so Xbox Series X Pro shouldn’t be far behind). While Starfield is a major reason, there is also Avowed coming up, and I have big hopes for that. Not to mention Fable.
Also, I’ve never had Xbox so want to play older franchises too. So, Xbox makes sense to me. Your requirements might be different.
