From the Nintendo Game Boy to the PSP and the Nintendo Switch, handheld gaming has come a long way over the years and has grown more and more popular. Although many people still prefer to play the big triple-A games on their home consoles, a lot of people love the portability of having a handheld console they can take anywhere with them.

While there are a ton of handheld gaming consoles that have been popular over the years, there are also a lot of them that just about everyone has forgotten about. Although some of these are fun for hardcore retro game collectors, most of the rest of the world completely forgot they were ever sold.

To see 10 handheld game consoles we've all forgotten about, keep reading!

10 Nokia N-Gage

The Nokia N-Gage was released in 2002 and was discontinued in 2005. This handheld console was Nokia's attempt to blend their already successful mobile phone line with a handheld gaming device and unfortunately, it wasn't exactly successful in either regard.

This device only sold a few million units before it was discontinued and although it had a number of popular games on, including Call of DutyTomb Raider, and The Sims Bustin' Out, the gaming world has basically forgotten the N-Gage.

9 Sony PSP Go

Sony's PlayStation line of consoles is still really popular in the gaming world and even outside of their home consoles, their handhelds have been pretty big hits. The original PSP and the PS Vita have been popular among handheld gamers, but Sony has had its fair share of misses.

The PSP Go was released in 2009 and was designed to be a smaller, lighter version of the original PSP. Instead of having the buttons on the main body, it featured a sliding mechanism that would reveal the controls underneath the screen. Unfortunately for Sony, this version of the console was not as successful as the original PSP and was only sold for two years.

8 Watara Supervision

Released in 1992, the Watara Supervision was designed to be a competitor of Nintendo's Game Boy. When it hit the shelves, it had a price tag of $49.95, lower than the Game Boy's price of $89.95, something that the manufacturers hoped would inspire people to buy it instead of Nintendo's handheld.

This console was unique because it could be linked up to a TV and played like a home console, something else that set it apart from the Game Boy. Unfortunately, without a lot of the big-name games that Nintendo had, this console was mostly ignored by consumers and game developers and has since been forgotten.

7 Tiger Electronics' The Game.Com

OLYMPUS DIGITAL CAMERA

The Game.com console, pronounced "game com," was released in 1997 through 2000 and was the first handheld game console to have Internet access and to feature a touch screen, pre-dating the more popular Nintendo DS.

Unfortunately, despite being heavily advertised and a pretty unique handheld console, the Game.com suffered from some seriously lackluster sales, As attempts to revamp it just didn't bring in the buyers, the console was discontinued and forgotten by the gaming world.

6 Atari Lynx

The Atari Lynx was known for being the first full-color handheld game console and was sold from 1989 through 1995. This console played games from cartridges and was manufactured by Atari, an already big name in the world of gaming at this time.

Unfortunately, despite the Lynx being a relative success at launch, the fact that it was released so close to the Game Boy's release and the fact that Atari started to shift its focus away from this console toward the end of its lifespan meant that the Lynx has mostly been forgotten in favor of other retro consoles.

5 Sega Game Gear

The Sega Game Gear was sold from its launch in 1990 through 1997 when Sega discontinued the console. The Game Gear was marketed as a handheld version of the Sega Master System and was designed to compete with the Game Boy with its portable form and full-color screen.

Unfortunately, critics weren't happy with the Game Gear's short battery life or that the console's library lacked a lot of original games that couldn't just be played elsewhere. This, paired with the fact that Sega spent much of the Game Gear's lifespan focused on other projects, lead to this console being forgotten.

4 WonderSwan Color

The WonderSwan Color was developed by Bandai and released exclusively in Japan in 2000. Along with the original WonderSwan and the SwanCrystal, it was one of three handheld consoles in the lineup that was sold from 1999 through 2004.

This console was popular in Japan because of the large library of licensed first-party games, many of which were based on popular anime at the time. Unfortunately, the fact that this console was only released in Japan helped it to be largely forgotten by the worldwide gaming community.

3 Xperia Play

Prior to the release of the iPhone, mobile phones were pretty unique in their design and features. Although the N-Gage may be one of the first mobile phone-game console devices many people think of when they reflect on strange mobile phones, it wasn't the only one.

The Xperia Play was released in 2009 and was discontinued in 2011. The game was originally rumored to be a "PlayStation Phone" but was rebranded before launch, though it did feature a similar design to the PSP Go and allowed players to play various PlayStation and PSP games.

2 Bit Corp's Gamate

The Gamate was a handheld console by Bit Corp. This console was released in a number of different regions in the early 1990s but was discontinued not long after launch.

Unfortunately, this console was easily outsold by Nintendo's Game Boy and other handheld consoles of the time. Today, this console is mostly forgotten and its approximately 70 games have become tough to find.

1 Tiger Telematics' Gizmondo

The Gizmondo was a handheld console launched by Tiger in 2005 and discontinued just over a year later in 2006. Under 25,000 units were sold during this console's incredibly short lifespan, so it's easy to see how this console has been lost to time.

Around 14 games were released for the console, with six at launch and eight others afterward. Although there were over 30 games that were reported by the manufacturer to be in development for this handheld console, none of them ever hit shelves because of the manufacturer going bankrupt and the console being discontinued.
