Just got my first entry level gaming pc! i have about 30 bucks to spend, what should i get for it?

I have all my hardware set up, including a new chair. MineCraft and baulders gate 3, terraria, and some freebies are my only games so far. I have a massive console and physical game collection that I love, so I’m really just looking for things that are definitively better on pc, only on pc, or software that I may not know...
