Maybe don’t get a ps4 pro, but a normal PS4. Look for a deal, bundle, or even used one at stores like GameStop, Best Buy, even eBay. Always check return policies and make sure it works before you buy.
Same for those games. Get them used. Those stores you can buy used games, and still return them within a week to get a full refund. Then if you see it cheaper elsewhere, get it there instead.
Keep in mind f you want to play online, you’ll need ps plus, which is $60/year.
But if you really want to play those games, then it’s worth it to you. Then maybe you’ll start splitting non exclusives on both consoles as you get more familiar. And have more options to save money on potential deals.
