I dont know much any of blockchain games but as far as I know you must have invested good money in order to get good items just like normal game we used to play. But the good thing about blockchain games is that you can earn money because most of them give items for marketing promotions.
In terms of playing the game it is not all the same, especially in the case of blockchain games, because basically all the game players want to make a profit through the games they play, if someone can't play them well, then they will always lose and lose.
