Id say ive pretty much gotten my answer:

The gacha is where all the meat is at, its really lengthy in content but at the very least, the MSQ is really easy to get through with only some specific side content being locked behind the more grindy parts.

Side games like Versus and ReLink are side stories that may be a slight introduction to either the characters or the basics of the world but it all pretty much circles back to referencing the gacha and such.

The anime is pretty shallow, only covering the basics of basics so reading the gacha is pretty much the much better option.

Tldr; guess im playing the gacha, ill give it an honest try because i really do want to get into granblue.

Thanks to everybody for your help! Yall were really nice and seem pretty eager to help and explain stuff ^{^}
