Why haven't they released the Cho Aniki games on any digital storefront? I think they should get the attention they deserve, M2, here is your next project.
Well, there's always the new
Cho Aniki rhythm game for smartphones...
Seriously, though,
Cho Aniki and the rest of Masaya's catalog, including
Langrisser, are owned by Extreme Co., Ltd. The company has released stuff on consoles, such as the (lackluster) remake of
Langrisser I & II and published various older works as download software going back to at least the Wii U. They're also the company behind
Gley Lancer and
Gynoug on the Switch. That said, Extreme's focus seems more on the mobile market and managing IP, rather than actively creating games. I'm not certain to what extent they really develop in-house, rather than subcontracting to outside firms.
Considering how much Extreme rides the
Cho Aniki franchise in their corporate marketing, I am surprised some of the games haven't appeared on more recent download platforms, though
Cho Aniki and
Ai Cho Aniki are available on Japan's Project EGG service. As for some manner of decent retro collect, the question is probably whether there's enough of a market to warrant that type of treatment. I quite enjoy the
Cho Aniki franchise, but I'm more inclined to think the best the series would see is some moderately-priced, emulation-based collection, instead of one along the lines of M2's ShotTriggers.
Otherwise, you can always watch a TV commercial, where Adol and Samson pimp Extreme's contract-worker business:
