When it comes to the actual utilitarian use these things are good for about three things scaring noobs on the beach as you roll up with 20 following behind you or, egg layers which produces kibble for the pelagornis. The last is a special attribute of all shoulder ridden dinos, all the weight the compy carries is reduce by 1/2 when shouldered.
I wish there was like an attachment like a camera or something attached to a tamed compy’s back. And you can control it and look around through the camera while using the compy to run around and look. I think that is a good way to scout a tribe I wish there was something like this in the game. The camera needs gasoline to be activated just needs to be put in the compy’s inventory.
For practical uses that is. Compy’s are the housecats of ark. Tame one and set it on wander inside your house and you have endless companionship. It’s dumb, and really impractical seeing as you probably have tons of other games to keep you company, but it’s still nice to see a tiny little dinosaur run around your home.
