Konami surprised and delighted fans of the Teenage Mutant Ninja Turtles and beat-'em-ups alike with its announcement that a slew of classic TMNT games would be bundled in a package called The Cowabunga Collection. Hosting nostalgic hits like Turtles in Time, this bundle is made further enticing with added online gameplay and other bells and whistles like button mapping. And with the addition of save states, disgruntled players of the NES platformer from '89 finally have some hope in making it through the technodrome in one piece.

With this bodacious celebration of the heroes in a half-shell—and old-school gaming at large—gamers' minds have run wild with other potential retro bundles. While the list of great options is sizable, these are some that should best fit the mold.

8 Battletoads

Rash in Battletoads

Like the reptile-based franchise, it partly seeks to emulate, Rare's thrilling retro game of fighting amphibians would surely be a smash-hit. And the British studio has already proven it can craft a great remastered compilation of retro gems, with 2015's Rare Replay.

While the series has been revived by way of a 2020 sequel, fans would no doubt thirst for Battletoads at its peak, given the mixed reception of that game. The package would of course highlight the breakthrough debut from '91, but could flesh out the content with the lesser-known Double Dragon crossover, SNES' Battlemaniacs, and the Game Boy spinoff. Diehards can enjoy the grueling gameplay this brawler has to offer, while less-seasoned tadpoles can be eased into the action with an easy mode and rewind feature.

7 ToeJam & Earl

This zany alien romp from Johnson Voorsanger and Sega finally saw a sequel with 2019's Back in the Groove. This retreading of the nostalgic 90s hit for Genesis was mostly well-received and showed the great potential of four-player jammin'. Such a feature would naturally be welcomed for the fan-favorite original, which could easily be added in a remaster.

Moreover, this scant-but-memorable series would seem to lend itself to a compilation—with diverse gameplay styles rounding out the lineup. The sequel, known as Panic on Funkotron, pivots from isometric scavenger hunt to 2D platforming. Meanwhile, the Xbox's Mission to Earth (which is missing from the bare-bones ToeJam & Earl Collection on XBLA), treads into 3D-adventure territory.

6 Bubble Bobble

Sure, it may be obscure for most younger gamers, even after the release of a modern rendition for the Switch, PS4, and PC. Yet, there was a time when this charming arcade game from Taito was one of the best ways to enjoy simultaneous multiplayer. There's something timelessly fun and rewarding about gathering foes into bubble clusters and popping them all at once for major points.

And given the popularity of couch co-op as well as online gaming, this bubble-blasting action romp would seem to fit the current gaming scene like a glove. One could get countless hours of bubble-popping fun playing the arcade classic from '86 and the elusive Bubble Bobble Part 2, which remains one of NES' rarest games.

5 R-Type

The 80s and 90s saw a bombardment of shoot 'em ups spanning a range of settings—though typically residing in the dark void of space—with R-Type leading the charge. But the genre has fallen out of fashion of late, which makes a return trip to this heart-pumping, celestial ride all the more sensible.

With several awesome titles to its name, gamers of all ages could find something to enjoy in this tough-yet-accessible Shmup. While slim, the two-game bundle/remake R-Type Dimensions gave fans a preview of what a truly fleshed-out, complete R-Type package could be like. Add some bells and whistles—online co-op, challenges, rotating events, and leaderboards—and the possibilities are sky-high.

4 Final Fight

Many would agree that retro beat-'em-ups make solid templates for modern compilations, with their timeless gameplay and multiplayer options. This is especially the case with this now-forgotten Capcom classic from 1989. Final Fight pummels players with straightforward-yet-endlessly fun combat and a diverse lineup of fighters with awesome moves. The experience remains accessible despite its age—with accessible controls and mechanics that resemble typical 90s fighting games.

The franchise would fit nicely into the modern scene, with its gritty style—and games like Scott Pilgrim Vs. The World and Streets of Rage 4 putting the genre back on the map. Of course, there's also the added factor of obscurity. While the original FF trilogy is well known and widespread, rarer titles like Final Fight One and PS2's Streetwise could be polished up and exposed to millions of younger gamers. A remaster could even have characters crossover between games and introduce new ones, as the limited roster marks a rare blemish of this otherwise-great brawler.

3 Metroid

Super-Metroid-Chozo-Statue-2

This sci-fi hit has been perhaps one of the most desired in terms of modern installments from Nintendo this side of Earthbound. Even after the release of Metroid Dread on Switch, this terrain still feels largely unexplored in terms of potential.

A polished, juiced-up remaster of Metroid classics would make a great bridge to the anticipated Metroid Prime 4 and remind fans what makes this exploration shooter so special. Players can get to blasting and bounty-hunting on hits ranging from the NES original and Super Metroid to the overlooked spinoff Pinball on DS. In an era rife with indie Metroidvanias, it would be great to get a celestial trip back to the epic that started it all.

2 Donkey Kong Country

Nintendo's prized ape mascot has seen no shortage of games since his iconic arcade debut in 1981. Often viewed as a sort of 16-bit renaissance for the mascot and platforming at large, Donkey Kong Country hit the scene with a bang; and has itself spawned modern sequels from Retro Studios.

But it's the original DKC that continues to shine—with sleek visuals, lovely tunes, lush locales, and tight mechanics that still hold up today. Seeing as these classics are a major draw to Switch's SNES online service, a modern package of this fan-favorite series would be more sought after than Kong's banana horde. The bundle could even be fleshed out beyond the original DKC trilogy by tapping into the lesser-known Donkey Kong Land spinoffs on Game Boy.

1 The Legend Of Zelda

The boss battle against Misery Mire's Vitreous in The Legend of Zelda: A Link to the Past

The Big N's esteemed fantasy franchise would surely be a coveted one, with a robust library of countless epics dating back decades. Switch's vibrant remake of Link's Awakening illustrates the huge potential of revamping even a more lukewarm rendition of Zelda.

But even with minimal refinements and additions, a compiliation of peak 80s and 90s Zelda could be legendary. Such a collection would shine like a Master Sword as one of Switch's best, most content-dense adventure games.
