Under most circumstances, our answer to the question "Should I buy a Dreamcast" is yes. If you don't have a Dreamcast, you should buy a Dreamcast. If you already have a Dreamcast, what if your Dreamcast breaks? What would you do then? Not play Plasma Sword, that's what.
But when that Dreamcast costs ¥38,000 ($469), we must be more reserved with our recommendations. That's the price PachimonTV gives to this handmade portable Dreamcast unit, shipping next month in Japan. We'll leave it to you to decide whether or not that's a fair price for the ability to play Shenmue on the go.
At the very least, it's a more elegant portable Dreamcast solution than the infamous Treamcast.
