Well... it IS sadly the best choice... you either get financially bankrupt getting into all the other absolutely not overpriced programms or you try to go with blender...

Going with blender is quiet ok if you like getting no help at all or random youtube video links, like:
"here you go all questions answered",
or you don't even get a answer at all 'cause your "newbish" question got removed for no reson... must be a mistake on my side asking for help in the first place...
So you search the whole damn web on your own, you know, the ""world" wide web" which leads you to one single answer on a japanese wiki side that provides more informations as the damn manual, which is absolutely not written by monkeys with internet access where you try to figure out what they even trying to tell you because WHY MAKING THINGS EVEN UNCOMPLICATED!
And then some informations turns out to be even wrong... or not...what do i know NOBODY HELPS ME!

So yeah if you were born with all the informations for 3d animations already learned you can start straight on, otherwise, good luck on your journey finding a answer to a problem wich someone propably can solve withing 2 seconds of taking his time.

Attention! don't trust the tags or some of the reviews, it is actually a horror game, 'cause it is a nightmare what they did to the series, i think i never saw more broken and horrofying lame content.

BUT it's not ALL bad, you might even enjoy it, if, you know, you are this kind of person with zero expectations that praise even a trash filled dumpster for how much fun it is.
