40. Dragon Ball Z: Legendary Super Warriors (GBC)

A strategic turn-based card fighter, Dragon Ball Z: Legendary Super Warriors launched in 2002 (in Europe first, funnily enough) and brought the series' colourful cast of characters to GBC in a thoroughly decent card battler.

39. Blaster Master: Enemy Below (GBC)

The mixture of old and new elements give Blaster Master: Enemy Below enough new twists to make it a worthy sequel to the amazing original. Sure, many of the same audio/visual elements have been carried over fairly unchanged, but the new bosses and open setting offer up a whole new experience for fans to enjoy. If you never gave the Blaster Master series a chance (and Switch owners don't have much excuse considering that both this and the NES original are available with a Nintendo Switch Online subscription), this great Game Boy Color title is as good a reason as any to get stuck in.

38. Mickey's Racing Adventure (GBC)

A great little licensed racer from none other than Rare, Mickey's Racing Adventure was the Game Boy Color precursor to Mickey's Speedway USA (which also received a less-well-regarded N64 counterpart). This one essentially combined the developer's isometric 8-bit racer R.C. Pro-Am (or more specifically Super R.C. Pro-Am on the Game Boy) with some of Diddy Kong Racing's adventurous spirit and stirred it all up with vintage Disney characters.

Featuring enormous character sprites wandering around a top-down overworld between land and water races, plus a host of puzzles and minigames, this is far more in-depth than your average licensed game. Worth investigating if you get the chance.

37. Legend of the River King (GBC)

The sequel might have expanded on this game, and Legend of the River King might be a short ride, but it's highly entertaining while it lasts; there aren't a huge amount of fishing-focused RPGs out there (for shame!), so the series is pretty unique. Besides, not every RPG has to be 200 hours. This bite-sized delight from Natsume is still worth casting a line for.

36. Mega Man Xtreme 2 (GBC)

Mega Man Xtreme 2 is a major improvement in every way over its predecessor. It looks fantastic, plays very well, offers a smooth and varied experience and draws from a whopping four Mega Man X games. This is much closer to the portable X experience that fans were looking for back in 2001, and while screen size, some minor control issues and a few unresolved problems from the first game contribute a bit of a drag factor, it's still an ultimately enjoyable experience.

35. Harry Potter and the Chamber of Secrets (GBC)

Building on the fine work of the previous GBC entry, Harry Potter and the Chamber of Secrets captured the spirit of the books (and subsequent films) far better than you might expect — and certainly better than the many lacklustre platformers and alternate takes on the source material that littered consoles for years to come. A gem.

34. Lufia: The Legend Returns (GBC)

Lufia: The Legend Returns is a solid entry in a series that really doesn't get enough attention these days. This is a big adventure with plenty to keep players occupied, and it looks good for a Game Boy Color title, with some impressive (if sometimes repetitive) music. It's by no means perfect and certainly has some issues, not least overly complicated menus, but the combat system is a fine one and it's still worth a look.

33. Rayman (GBC)

Rayman's Game Boy Color port absolutely has its charms, but it also has its share of irritations. Stiff controls, a confusing layout and a few troubling glitches mar an otherwise fine experience. It's still a lot of fun, and it offers some incentive to play through it again upon completion, but it's a port that sacrificed a lot of content in order to make the transition to handheld, and that leaves it feeling rather slight compared to the Ubisoft mascot's more celebrated platformers.

32. Crystalis (GBC)

Developed by SNK before it became the fighting game factory of the 1990s, Crystalis made quite an impression on the NES when it was released in 1990, and this Game Boy Color remake — coded by Nintendo Software Technology, no less — is viewed by many fans as a step backwards. Sweeping plot changes are involved, and there's a whole new soundtrack. The visuals are also a little cramped due to the Game Boy Color's smaller display. Even so, it's still one of the best RPGs on Nintendo's handheld, and if you're approaching it having never played the NES original (which is on the SNK 40th Anniversary Collection on Switch, by the way, and also features in the Nintendo Switch Online subscription lineup), then you'll find plenty to enjoy.

31. Survival Kids (GBC)

Best described as a cross between the TV series Lost and The Legend of Zelda, Survival Kids (or Stranded Kids as it was known in Europe) is groundbreaking in how much agency it affords the player; despite looking like your typical cute and cuddly RPG, it allows you to tackle the game at your own pace and in a largely non-linear fashion. Gameplay revolves around tracking various elements such as hunger, thirst, and tiredness, and there's even a crafting system present that enables you to create weapons and tools. Survival Kids is a standout GBC title and got a Japan-only sequel in 2000, and the series would go on to inspire the Lost in Blue franchise on DS and Wii.
