There is a demo if you want to try before you buy. Your progress carries onto the main game, too.
It's definitely worth a go, it's an incredible game and worth every reward it gets.

Self-Promos tend to be insta-ban due to how spammed and intrusive they used to be and still are. It's one of those "everyone gets the same treatment" situations.

Tbh I would take the plunge and get it.
It's an incredibly 'Adult' Final Fantasy with an amazing story. The action is slightly repetitive at the begining but as you get stronger going through the story you end up with more powers than you know what to do with (fortunately there is a highly customisable training mode to try out your new powers and come up with a skill set that suits you!).
I'm pretty sure this game will win Game of the Year awards!

Stellaris because I keep getting wiped out.
