I blew a few quarters on Arkanoid at Barcade last night, so perhaps I'm a wee bit saturated in nostalgia at the moment, but nonetheless: this paddle controller from Taito, which plugs into the bottom of the Nintendo DS for use in games like Arkanoid and Space Invaders Extreme, sounds great. Sure, you could fake it really well with the DS's touchscreen, but read out what Chris Kohler, who got a hands-on, had to say:
it's fantastic. It's not just a little plastic dial. It's sitting on ball bearings or something, and it's got momentum and a little bit of kickback to it. That means that it spins incredibly smoothly -- if you spin it and let go, it'll keep whizzing for a good five seconds or so. The response time is perfect.
Yet no plans for a North American release! Criminal. They'd sell dozens.
