SAGAS boasts that you can recreate any world and bring it to life using the system and so far, it hasn't been proved wrong. I've enjoyed playing in a Cryptid Fairytale World, Studio Ghibli inspired World, JJK, and even a One Piece world where our crew sailed the South Blue.
The system is relatively easy to learn for new players and creating a character can be done in 5-10 minutes. What you really need to get used to when playing SAGAS is getting unnaturally excited to roll natural ones.
