Despite the hype surrounding NFT games, the games themselves and the play-to-earn model have been heavily criticized.
One frequently voiced criticism of blockchain and NFT gaming is the burden it creates on the environment. Transactions with non-fungible tokens, such as creating and selling NFTs or bidding on tokens, require blockchain calculations. These, in turn, consume large amounts of electricity.
Currently, most NFT games run on the Ethereum blockchain. The popular altcoins blockchain uses the proof-of-stake algorithm. This significantly reduces energy consumption, making NFT games more environmentally friendly.
The play-to-earn strategy has also faced considerable criticism. With traditional computer games, users are required to pay a fixed fee. Registration for NFT games tends to be free, but to have full access to the game, players are often required to purchase tokens or NFTs. Because the gaming market and cryptocurrencies are subject to extreme fluctuations, investments in NFT games are speculativeand risky.
