It's always worth poking around the NTT DoCoMo stand at Mobile World Congress, and this year is no exception. The Japanese mobile operator has a couple of next-gen handsets with a gaming angle.

First, there's the company's prototype projector phone, which lets you project the handset's display onto a wall or screen at high-resolution.

Here's a murky shot of it projecting a Capcom game (the murk was caused by a flickery light, not our poor camera skills):



No word on when a commercial device may go on sale. Second was the intriguing 'seperable phone' - a handset made of modular keypad and screen which come apart.

In a gaming sense, this means you might have a separate gaming keypad (shown below) that you switch in when playing – while also placing a bigger screen propped up in front of you for a more TV-like experience:



Again, it's a prototype for now.

DoCoMo was also showing off its line of 'Mega Games' – rich 3D mobile games up to 2MB in size, like Bandai's Mobile Suit Gundam U.C. 0079.

Meanwhile, games are also a factor in the operator's i-appli online suite of web apps for its handsets. These also included rich online 3D titles like Sega's Cyber Troopers Virtual-On, Capcom's Lost Planet and Genki's Shutoko Battle Online.

However, DoCoMo is also selling more casual multiplayer games like Tetris League.

Finally, games are included in the firm's i-Widget widget platform, with Digital Chocolate's Tower Bloxx Mini one of the highlighted titles.
