An article on CNN.com talks about a gaming system released by VG Pocket. The game is a portable gaming system that has games pre-installed on it, so game cartridges are unnecessary.
Two different types. The first is called the Tablet. It is about 3 inches in diameter and comes with 25 games. Although the product has sound, it does not have a headphone jack. Also, there isn't an option to save progress in the middle of a game. The second system is called the Caplet, which is 7 inches wide. This system is $10 more but includes 10 more games and a headphone jack, as well as a wider screen. Both rely on AAA batteries, unlike other portable gaming systems which rely on rechargeable batteries.
Both systems are available in different colors, and have graphics that are very much similar the graphics of the games they're supposed to resemble, but with generic music. One major feature of these systems is their ability to hook up to a television.
A list of some games include:
Frogger
Lord of Jewels (A Tetris-like game)
Mutant Hunt (Similar to the game 1942, a World War II-based game)
Battle Blocks (Resembling Arkanoid)
Sudoku Quiz (Based on the widely popular Sudoku games)
Billiards Master (A two-player game of pool)
-----
Games exclusive to the tablet:
Space Invaders
Burger Time
Bust-A-Move
Adventures of Waldog (Like Super Mario Bros.)
Magic Jelly (Like Bomberman)
I've seen systems very similar to these in the past. I remember seeing a little system that had a joystick and a single button, resembling an arcade. It was all confined to one little box, and this box didn't have a screen, but connected to the television, and turned the television into a mini arcade. This kind of system only had five or six popular arcade games, including Ms. Pac Man, Galaga, Galactica, Dig-Dug, and a couple others. Although these games are still fun to play and are good, cheap alternatives, they'll never replace their more expensive counterparts. --Not that they were meant to.
These kinds of games capitalize on the market of kids with little money who still want to play games. They are relatively inexpensive ($30 or $40, depending on the system) which is nearly half the price of a Game Boy Advance. Even after being on the market for several years. Also, kids don't have to worry or fuss with buying new game cartridges. They have everything they need in the little tablet or caplet. Game cartridges for Game Boy or PSP can be as expensive as $50 for popular games.
A bonus is that the graphics are only slightly pixilated when displayed on a television. I'm not sure if Game Boy or PSP have TV-out capabilities, but if they do, they don't capitalize on them. I've never seen anyone hook up to a TV through a Game Boy or PSP, so I don't think they can hook up. I've heard that the Game Boy can connect to the tv via a Game Cube, but the Game Cube is yet another system that would require even more money.
A major downfall for these VG Pocket systems is their inability to save data. Maybe this is okay since the games are pretty retro, and don't require too much saving, but personally, saving data is something I really enjoy about Game Boy games. I can play for a little bit and save progress.
Although these systems aren't something I would invest mymoney on, I think they do provide a simple, but enjoyable (I think) alternative for portable gaming systems. As with every system, these VG Pocket games have their pros and cons. But for someone who either has the money, or in some cases, someone who doesn't have the money for something "better," they'll work as a sort of replacement or alternative.
