Is having tails in Minecraft really that big of a deal?
In my opinion, that is a dumb question.
Jk.
I think it would be neat, aesthetically, mainly because I like making my avatars for games representative of me. But it would be cool if a "more player models" mod was made that gave you different qualities based on models you add.
Like if you gave yourself wings, you could fly, but you would move slow and lose hunger faster. And use of a mod/plugin that could let you train your speed, health, and more would add a nice incentive to the game.
