Nothing beats having the ability to personalize the character or weapon you play to your liking or having something set you apart from everyone else playing that champion. Because of this, many games, especially online ones, have skins.
Skins are cosmetic items you can apply to your characters or their weapons to make them appear different than they usually would. While most games have you pay in-game premium currency to buy skins (such as Overwatch 2), some allow players to win skins using other methods, such as getting skin shards from Hextech chests in League of Legends or completing agent contracts in Valorant to be rewarded with weapon skins.
Unfortunately, in most cases, the only way to get a specific skin you want is to purchase them using an in-game currency, usually premium currency that you have to buy using actual money.
In a majority of games, skins do not do anything to affect your gameplay and are purely for aesthetic purposes. Despite that, developers such as Riot get a huge chunk of their total revenue from players purchasing skins.
Skins in games like League of Legends, Dota 2, Valorant, and Counter-Strike: Global Offensive are typically considered to be cosmetic items, which means that they do not provide any gameplay benefits or advantages to players. Skins are used to change the appearance of a player's in-game character, weapons, or other items, and they are purely for aesthetic purposes. While some players may value certain skins highly and may be willing to pay a premium to acquire them, skins do not provide any advantages in terms of gameplay. This is to ensure that the game remains fair and balanced, and that players cannot gain an unfair advantage by purchasing skins. However, it is important to note that some games may have special skins or items that do provide gameplay benefits, but these are typically not considered to be "skins" in the traditional sense.
