I would say yes and no. It is a game about evolution with some similarities but it is very focused on a realistic representation of evolution. This makes it a more complex game than spore and actively encourages many different niches not just agressive, peaceful and mixed as spore did.
Aldo currently they are working on finishong the cell stage and the beginning of the multicellular stage while have more in deapth discussion about the transition between the microscopic and macroscopic phases among other things.
It’s free, so don’t let that stop you, but it is very fair if you want a more complete experience before trying it out.
(It is paid on steam as a way to suport the game, but free downloads can be found on their website)
