Just about any shonen anime/manga is ripe for this, on the condition that they use the world/setting to create something unique and don't just retell the story for the umpteenth time like Dragon Ball or Naruto do. When Yu-Gi-Oh! got like a full-blown RPG on the GBA, for example, that was real cool - as was the Pokemon TCG game that had ultimately inspired it.
Something like Yu Yu Hakusho where you're an actual spirit detective doing cases, maybe sort of like the first SMT Raidou Kuzunoha game but infinitely more polished and refined, would be fucking fantastic. Gurren Lagann just begs to be exploited and to have some utterly ridiculous, universe-faring RPG bullshit of infinite escalation - and may be a case, if done well, of just following the narrative beats and filling in blanks for downtime being sufficient.
And an actual, honest to god attempt at a Power Rangers (or Super Sentai, I suppose) game would be great. I really enjoyed some of those back on the SNES/GEN, and you can do so much with the ongoing comic book beyond the fighting game I'm not at all interested in. Everything from Musou-style, to J-Action/Character Action, to RPG could work really well depending how much material they used and what they did with it.
I wasn’t trashing them by any means, it just seemed like they copy/pasted the same formula for every game… it was more about blatantly capitalizing off of the movie or show than playability.
I didn't realize it at the time, but boy did The Cowabunga Collection reveal how blatant it was. TMNT2 Arcade (NES) and Turtles in Time (SNES) were the two I always loved, but the former basically existed as, I don't know, 4~5 different games and the latter (alongside Hyperstone Heist, which I didn't play back then) was more of a Greatest Hits than a unique game. Still absolutely incredible, even today, but... yeah.
Licensed games were weird, though. Like back on the SNES and GEN I would say typically licensed games were amongst the best available - things like Castle of Illusion, Aladdin, hell even some of the Jurassic Park games come to mind - and then later on, probably somewhere in the PS1 generation but
definitely by the PS2 generation, were
generally synonymous with garbage. And then we had a sort of resurgence with things like Batman Arkham, but... most licensed games are still poo.
