You can play 'Crazy Taxi' on your smartphone for free

If you've always been intrigued by the early noughties appeal of Crazy Taxi, but didn't want to lay down cash on that curiosity, you now have no excuse.

It's been eight years since Victorian London was swept underground by a swarm of bats.

'Fallen London' and the secret to writing an infinite gothic game

Fallen London is a deep choose-your-own-adventure game that debuted back in 2009, with no moving pictures to guide players into new worlds. Instead, it's text-based, allowing fans to decide how they'll react to certain scenarios while they wander around a Victorian version of London that's trapped in an underground dimension. It's still available in browser form, but it's also on iOS and Android, spawning a successful spinoff mobile franchise in the process. Just this week, Failbetter Games announced it would place renewed focus on Fallen London, tying up some of its stories and systems. The lore is probably unlike any other game story you've experienced before.

With a 43-yard aperture, this promises to be the world's largest optical telescope for a long time, even compared to future projects.

Infinite (battery) lives

USB-powered Sega Nomad gives you near-endless game time

Sega's Genesis Nomad was always a compromise: It ran 16-bit console games on mid-90s handheld tech, but took six AA batteries just to get three hours of playtime. Wouldn't it be nice if you could use modern hardware to play without constant (and sometimes expensive) battery swaps? The Sega Holic (aka Catch22 on NeoGAF) thinks so. He just teased a homebrew Nomad modification that lets the portable system run on USB power.

But wait, there's more...
