Once, I tamed a gallimimus, then he got 14 levels of Tame so I upraged only speed movement, I named it dragster, I went to search Iron ore then two raptors attacked us, dragster just flee at extreme speed and I don't know where is she
My tribe and invented a special activity free time activity including the Galli.
We have teams of three, each one has a Galli, tranq arrows and (cross)bows.
Then we search a wild mid/endgame Dino (Sarco, Allo or Yutyrannus for example)
and start riding around it /away from it while shooting it and trying not to leave a specified area.
If you knocked out your target first and stayed in the area, your team gets to tame said knocked out creature and resources from the other teams.
You can take these activities to a higher level with competitions within your tribe, or even do tribe vs tribe tournaments with one team having 5 Galli crews and the hunting target being a Giga...
