The thing I'm worried about is I think these games haven't been updated and will die on the new iOS11. I'm pretty sure I recall the "this game will slow down you phone" message for both games. Because of that I've actually put the game progress on hold for the mean time. I'd be glad to be proven wrong but I'm sure these games are under the old app infrastructure. I've also been waiting for the next Agarest to be ported (the one I want to play the most) but seems like they've given up on that with no updates or contact.
The "won't work" did come up on my fresh install. On this one I'm prepared to take the hit as I've been wanting to play it. Apple should really warn us before they take our money not after.
I submitted two support messages to the devs several months apart about the 32bit issue. No response still. I'm disappointed, I really wanted to play the game on iOS.
Don't know about you guys but I'll buy both Agarest War games just because: 1) They're on sale. 2) I've never played eastern tactical RPGs.
All of Hyperdevbox's games are 32-bit only and they've told me that they can't update any of them for 64-bit compatibility due to issues with the source games. So buy at your own risk.
I suggest you go get Final FAntasy Tactics instead. It's an eastern tactical RPG, it's one of the greatest games of all time, and it's getting a 64bit, iOS 11 update. http://toucharcade.com/2017/08/02/square-enix-confirms-final-fantasy-tactics-will-be-getting-64-bit-update/
