WonderSwan
Don't let the fruity name fool you -- Bandai dedicated almost 100% of its floorspace to its just-released black-and-white handheld. There are many reasons to pick up one of these things: Size, Cost, and Support. The WonderSwan is amazingly small, almost smaller than an average adult's hand. It averages on the streets in Japan for around Yen 4800 (which is around $45 bucks in the States) and the games cost about $25. There are more than 30 games in development or available for the system, including Chocobo's Mysterious Dungeon by Square, Beatmania by Konami, and even a version of Klonoa. What's more, Bandai promises Dreamcast and PlayStation connectivity in the future in some fashion, much like an enhanced VMU or PocketStation. While the graphics aren't nearly as pretty as Nintendo's color handheld, the system offers more variety. And it just looks really, really cool.
Neo Geo Pocket Color
Almost six months ago, SNK released the Neo Geo Pocket handheld, a black-and-white system with a fistful of software support that just didn't garner enough sales. Well, today is the day the Neo Geo Pocket Color hit the streets in Japan, and SNK's booth was filled to the brim with systems and games.
The system is about the same size as the Game Boy Color, but has a bigger and brighter screen (it's not backlit, though). There are a few games for the system, including Puzzle Bobble Pocket and Baseball Stars Color, but these games just have a very rushed feel to them, and there isn't anything the system does that the Game Boy Color cannot do, which makes the Neo Geo Pocket Color's Yen 8900 pricetag a bit hard to swallow. The system does promise Dreamcast connectivity in the future.
Since Nintendo did not partake in TGS, Game Boy presence was limited to third-party titles.
