The first example I can think of this is the Bionic Commando reboot in 2009. It was released alongside a modern interpretation of the original, 2D game, Bionic Commando: Rearmed that was very well received. So much so, that Rearmed got a sequel while the ostensibly mainline game got forgotten in obscurity
We also have Ion Maiden, an old school FPS made with the Build Engine used for Duke Nukem. They are basically building the game with the same tech as back in the day, the only change is they updated the engine to run in 64-bit computers. It started as a companion piece to Bombshell, a totally mediocre Diablo-esque action-rpg thing that also got forgotten pretty quickly.
Ion Maiden looks to be far more interesting than the game it spins off of
Even the art direction and promo posters are more inspired in Ion Maiden

vs.

(these are both the same character)
Lastly, we have Bloodstained, IGA’s post-Konami IGA-(non)-vania and the NES-esque counterpart Curse of the Moon.
Considering what has been shown of Bloodstained and the high praise that Curse of the Moon got on release, it seems we are in another situation where the spin-off sub game ends up being better than the main release.
What happened? Is it because old-school, tried and true designs are inherently better than more modern, 32-bit generation type genres? Do we just prefer them because we’re getting old? Are there more examples like these on the horizon?
