Dragon's Dogma 2

Microtransactions in Dragon's Dogma 2 are summarized as...

This game is singleplayer only and full priced, yet it features a large amount of microtransactions.

Most of the microtransactions relate to items that give you an advantage in-game, or provide services that you would otherwise get for free in any other game.
For example; you can change your appearance in-game through a special currency which takes a long time to collect, but can otherwise be purchased directly.
Another example is Fast Travel, which costs the same currency and is fairly expensive. The developers played this off as Fast Travel being unfun, and having to work for it is more rewarding. Only for them to put in microtransactions that allow you to bypass this work.

It should be noted that while many of these items can be purchased via in-game means and are not necessarily locked behind real purchases, it is done in a way to inconvenience you. The developers chose to make it inconvenient not to make the game more fun, but to get you to spend money.

The game features a Deluxe Edition which includes nothing but some of these microtransaction locked items.

These microtransactions were intentionally hidden from reviewers and were only added when the game was released for consumers.
