I would say the purely in-game stuff isn’t necessarily worth it to me but to the extra stuff like the artbook and soundtrack (even though I doubt I’ll use them that much) make it worth it for me. In all honesty tho I probably would’ve bought it without those include
An interesting point is comparing this poll with one I ran on Yes or No thread a few days ago
RIP to that 33% that bought something they though wasn’t worth it 
(btw I know that’s not necessarily how stats work but shush)
