What are the best exploration based games on PS4?

You can buy bundles of in-game currency, which can be used to gain an advantage in multiplayer. This makes multiplayer not fun for the players who don't intend on spending extra money. It also makes it boring for the ones who spend the money. Both of these things negatively impact the longevity of the multiplayer.

Some of the bundles go for $79.99, which is more than the game's price. It's sad seeing Konami milk their fans with microtransactions like this.
