I'd really like tameable animals. Horses, camels, elephants... Hell, even bears. Imagine ten guys on armored bears running at you. And behind them five war elephants, coated in leather armor.
Even tameable hawks and eagles, maybe. Or crows as sentinels. They'd fly over to your position or make a special "caw" to alarm you that somebody's on your turf.
I think it would be something special.
What game are you playing?
It's obviously not Rust if you think these things would mesh with the game.
I could see horses... maybe. Even that's a stretch for me. It's not as simple to tame a wild horse as slapping a saddle on it and hopping on.
And taming bears? Riding armored bears?! War elephants?! Man with all of these tameable creatures no one would ever have to fight anymore, just send your army of beasts after someone.
Silly, just silly.
