it depends on what you want out of it

I’m 33, I played it when it came out and I played it again last year.

The game is still pretty fun if you like designing dumb alien animals with its weird mechanics for the creature stage, making a weird little tribe/society, and get to the space stage and want to terraform little planets and then go find earth, and the center of the Milky Way.

I wasn’t even particularly young when I played it the first time, I was a post Halo 3 16 year old lol.
