I think EOH could have had more content. I don't find EOH bad since alot of the characters fits more well than in ASB, but theres just some flaws that makes EOH not as good as ASB:
1) It's Story is boring (And Araki wrote it? I guess they made him rush it)
2) Too easy unlockables, Its not like ASB where you unlock them and are required to buy them to use them. In EOH, you can get in Story without been required to pay them (When i got S on all missions, i had 5 million JP and i payed those i didn't get and i sat with 2 million left). Sure in ASB it took more than 4 month to get all stuff, but in EOH it only takes 1 or 2 days to get everything.
3) Lack of an Arcade Mode
4) No offline versus with other players...Thou this is understandable since its an Arena and split screen would be strange.
I can just say that aside from the flaws, i still enjoy EOH and believe or not, but i want a third Jojo Fighting Game...With the same style as EOH.
