Assassin's Creed Valhalla
Microtransactions in Assassin's Creed Valhalla are summarized as...
Assassin's Creed Valhalla is a full-priced singleplayer game. It contains microtransactions as if it was a free-to-play multiplayer game.
Microtransactions need to be purchased via a premium currency. The quantities you can purchase this currency in almost never matches the cost of the cosmetics themselves, making sure you always pay more for less.
Many cosmetics only come in bundles, forcing you to pay for more content that you might not be interested in. These bundles are often priced high, costing just as much as the games' DLC, despite receiving just a handful of skins.
Not all items are cosmetic only, you can purchase in-game gold, xp-boosts, weapons, treasure maps, materials, and many more gameplay altering items.
Despite the large amount of microtransactions the game also features some very expensive DLC. There are 2 DLC that are 25 USD each, or 40 USD total if you purchase the season pass. There also is a largely expansion type DLC that is priced at 40 USD. All 3 pieces of DLC together are more expensive than the base game, despite offer far less content.
