Yeah I never really cared about the handheld games or Revolution. They were TOO anime and tropey. Literally the only ones I enjoyed were 1 and 4, both of which I think played to the strengths of the setting AND the fairly unique gameplay.

Bear in mind that the series was already basically dead after the handheld titles until Sega decided on a whim to release a PC port of the original and it became wildly popular, which basically spurred the production of 4.

I wouldn't entirely write it off for that reason alone. I suspect the only chance for a revival at this point though is if Sega dies and the IP gets picked up by a more competent publisher.
