I still don't understand why someone would buy some virtual kitties, so it wouldn't be a surprise if someone is interested in buying some virtual avatars. To me, it's yet another attempt to earn some money by selling some worthless shit.
I think its because of their habit. Some users are into gaming that focuses on avatar leveling. In this case, ubisoft integrate a platform where users can attain that level of satisfaction. Maybe it is an attempt to earn cause they are gaming and business firm also.
We see how cryptokitties clogged the network but this time its another gaming platform will try this mania. Hopefully this will be a healthy ecosystem and would not resulted to same event like cryptokitties in the past.
The biggest problem with these collectibles is that they lack any utility, it's just a tokenized picture that you can maybe use to create more pictures.
Completely agree with you. Lack of utility means its only for satisfaction of having cute avatars. But some users will probably like these as observed in the past experience with cryptokitties.
