CryptoKitties is an enjoyable, but expensive game. This blockchain game is self-centered in breeds, collections and beautiful creatures that are all called CryptoKitties. Users can create their cats and then sell them to other players at high values. However, prices depend on the Cryptokitties themselves, what so unique they are. It has become one of the most played games, but it does not offer good benefits. It's also difficult after registering because it requires users to download a wallet to save all assets, but they cannot use their own. Let's remember this is a blockchain game supported by Ethereum, so all transactions must occur only with this altcoin.
I've noticed people like this game because it offers some rarities of not common games. First of all, each cat created is different to any other, it cannot be copied or edited as well as deleted or destroyed. Once they are created they are saved on the blockchain, and of course it could be updated, but after having achieved a great advance on the game. In general, this game offers players just a few free tutorials and usages, but it is paid at all, which makes it expensive and different from other blockchain games.
