Okay, so, I'm not usually the type to buy microtransactions. But I absolutely love steampunk style robot animals. And this reminds me of the clock work dog from Fable 3.
Most skins are just that, skins.
But someone actually took the time to make sound effects with this skin, you will hear mechanical noises with this skin for every action you normally have for your little feathered friend.
That, is going the extra mile.
In my opinion, this is worth a buck or two.
If you are, on the fence about getting this, dont worry you don't NEED it, it does nothing to change the core game.
But if you like steampunk stuff, you might enjoy this.
