I don't know if this idea has come up before, but pets seems like a good idea. Possible ways to get them could be: ●Buying from an NPC, or in return for an item ●Taming with bait items ●And developing on the 'Abandoned Space Station' idea, freeing one from the zombies:alien: on board. You could have armo(u)r and/or weapons for pets to increase their damage if they fought for you. Also, maybe feeding pets gives them 'stat points'to improve their skills. Finally, I thought there could be houses for pets like a dog has a kennel. Some houses would have different effects on different species, as would your character. For example, the Robot race could be a good combination with Mechanical pets, but not so good with Forest pets. Just an idea, plenty of points to expand on!
