As others have said, I would take my time before buying another game. Play the ones you’ve already bought a ton of times. That will get you a feel for the the style of game you like.
Then play as many others as much as possible before you commit to another purchase. Then you’ll have a better idea of what you want.
Patience is the key. Luckily you’ve got a solid collection of games to start. That’ll keep you busy for an awful long time.
