Tokyo Jungle

Each animal has its own set of tasks, which change only partially (by restarting you can pick up something simple) - you can view it in the pause menu in the Tasks tab. These are mainly tasks from the categories “do XY times” or “get to area X”. Difficulties can only arise with searching for specific objects with names. You can find descriptions of their locations and a map of all objects in this topic .

You can try the same dog as a robot, it has no tasks for reproduction, good attack/life/speed indicators. And he won't die of old age
