Are your favorite childhood adventures becoming outdated? Which monster-catching journeys need a modern revamp?

With close to 25 years of Pokémon goodness on the horizon, the series has become a worldwide phenomenon with over 100 games released. Spanning back to the original GameBoy, it’s staggering to see the graphical and gameplay differences between Pokémon Red and Blue, and Pokémon Sword and Shield. Nintendo has been gracious enough to bless us with remakes such as Pokémon: Let’s Go, Pikachu! and Pokémon: Let’s Go, Eevee!, but many of our favorite inappropriately named Pokémon partners still remain on our old systems.

10 Pokémon Conquest

Probably the most unique of the Pokémon spin-off games, Pokémon Conquest is a turn-based tactical RPG similar to Final Fantasy Tactics or Fire Emblem.

In the Ransei region, you’ll take control of six Pokémon on a dynamic battlefield and conquer kingdoms throughout the region. We’re yet to see a stunning Pokémon spin-off game on the Nintendo Switch, and this could be a perfect fit following the popularity of other strategy RPGs like Fire Emblem: Three Houses. Since we already have conquest, shouldn’t we get a “Pokémon Birthright”?

9 Hey You, Pikachu!

Hey You, Pikachu! is all we ever wanted as kids. Being able to talk to and interact with my very own Pokémon? Count me in!

Except, 1998’s voice detection was anything but barely functional, and the core game mechanics were built around it. In more modern titles, side features like “Pokémon Amie” allow you to take a break from stealing kids’ Poké Dollars to pet or feed your Pocket Monsters. With much better voice recognition technology today, Hey You, Pikachu! could become a fun escape with your favorite yellow friend.

8 Pokémon Pinball

Thinking about the creation of this mini-series, it seems inevitable that Nintendo would use the Pokéball mechanic and effortlessly translate it into an addicting arcade game with recognizable Pokémon filling the game board.

There were only two entries in the series, stopping at Pokémon Ruby & Sapphire. It’s a bit of a no-brainer to see that there are so many possibilities with which to revive the series, like adding multiplayer functionality, using earned in-game currency to upgrade your Pokéball or pinball board, all while incorporating some of the over 800 current Pokémon we know and love.

7 Pokémon Trading Card Game

In an attempt to translate the tabletop card game to the GameBoy, Pokémon Trading Card Game for the GameBoy Color places the player into a mysterious world where the inhabitants live and breathe nothing but card battles, as you familiarly collect gym badges and challenge the champion.

Earning new cards and customizing your deck becomes extremely addicting, without forcing you to spend your hard-earned cash on real booster packs. The series could use a much needed fresh coat of paint, especially since the Pokémon Trading Card Game 2 never saw the light of day outside of Japan.

6 Pokémon Black and White

Coming close to being a decade old, Pokémon Black Version and Pokémon White Version released on the Nintendo DS with a surprisingly dark story, memorable characters such as N, and a unique region with many new Pokémon.

While these games are relatively new compared to others, even having sequels, the Unova region’s towering cities and expansive overworld would translate perfectly into a 3D adventure as you squander Team Plasma’s mission to liberate all Pokémon across Unova.

5 Pokémon Mystery Dungeon

Pokémon Mystery Dungeon is the largest spin-off series in Pokémon history by far, and arguably the most popular.

The most recent entry, being Pokémon Super Mystery Dungeon on the Nintendo 3DS, shows that the cute dungeon-crawling adventures don’t seem to be stopping anytime soon. That said, 2005’s original Mystery Dungeon games would be a great option for the series debuting on the Nintendo Switch, featuring updated 3D graphics, polished modern gameplay, and even more inspirational quotes from our favorite Pokémon.

4 Pokémon Snap

Giving Pokémon fans a photography skill on their resume, Pokémon Snap is an odd concept for a spin-off, but its positive reception is nothing to scoff at.

Changing the formula for a rail-based shooter to photography lessons from Professor Oak himself is charmingly fun, as you strive to catch them all…on film. Applying these mechanics to modern gaming could allow the player to share their fantastic shots with other players, as well as spending hours to snap a super rare shiny Pokémon.

3 Pokémon Stadium

The first 3D Pokémon game came in the form of Pokémon Stadium on the Nintendo 64. It wasn’t much more than a battle simulator to be linked with Pokémon Red & Blue, but it was great for what it was.

As Pokémon games become more and more modernized on current hardware, the basis for Pokémon Stadium’s concept becomes a bit obsolete. However, disregarding everything but the battle system would allow for a modern Pokémon Stadium to focus on creating the most stunning visuals we’ve ever seen in the series, using its simplicity to its advantage and giving fans a game that we would never get tired of looking at.

2 Pokémon Diamond & Pearl

A gateway for many Pokémon fans came in the form of Pokémon Diamond and Pearl on the original DS. These games are regarded as fan favorites among many and remain one of the only mainline 2D games to not have a re-release.

Even when playing the enhanced Pokémon PlatinumVersion, there are a few glaring issues that highlight how outdated these games have become, such as the slower pacing and battle system. These games would heavily benefit from a modern touch-up and would sell like hyper potions.

1 Pokémon Colosseum

Combining Pokémon Stadium’s battle focused gameplay with the addition of a unique region and a double-battle focused story mode created a cult-classic in the form of Pokémon Colosseum.

There’s nothing else in the series quite like the gritty, steampunk Orre region, and literally stealing your opponent’s Pokémon. The game even opens up with a literal heist scene… You know, Pokémon stuff. Transitioned to a modern title, the game could replace the usage of your Pokémon from the GBA and instead allow functionality to Pokémon GO for HD battles in Phenac Stadium on the big screen.
