Expand Mermaids and Aliens
I think Aliens and Mermaids DEFINITELY need to be expanded way more. Vampires, spellcasters, and Werewolves all have skill trees with ranks and perks. Why can't aliens and mermaids have the same? Its very easy to say "just find a mod that does it" but why are there 5 occults and only 3 of them actually have depth to them? I feel like aliens are just there to look odd, be discovered angrily or confidently by a human sim, and chat about human foods, and mermaids are just there to play with dolphins, change the weather, and try to drown people. (I have played with aliens more than mermaids so I may be unaware of some of the things mermaids can do)
Like why can't they have skill trees?
I know they came in an expansion pack and weren't the main focus like Werewolves, vampires, or Spellcasters, but they shouldn't just be aesthetic landmarks in the packs they come from. I want some diversity between aliens/mermaids and their abilities. Maybe ranks wouldn't work, but at least give them abilities they can get with experience points?
