Kind of a weird question IMO. I don't even think animal lives are worth the same as animal lives. Is a single deer's life the same as a single ant's life?
I consider myself to be kind and thoughtful towards people and animals -- I'll save snails or worms that I find while gardening, but I also will kill mosquitos that are inside my house, and move spiders outside where they will potentially die.
This isn't even getting into "special" animals like pets
Age of Mythology. It's an RTS game from maybe 20 years ago, although there's a remastered edition that's less than a year old. I played the original version and the story and gameplay are both really fun. The controls definitely feel dated and clunky to me now though. I've not played the new version but I expect it's good too.
Specifically, you can play as Norse, Egyptians and Greeks with three main gods and nine(?) minor gods from each pantheon. You build up your civilization / town over several ages, managing your resource gathering and armies. Each age unlocks a new god with a new god power. Each god also has different mythical monsters that you can create such as jackals, hydras, wolves, etc. The original also had Chinese and Atlantians (Greek titans) as DLC, I don't know if they exist in the new version
