Steam

Check out this Destructoid blog post chock-full of delicious Cave Story-related goodness, including details on future Steam updates (leaderboards!) and an upcoming (a month!) eShop release, as well as a good word on Wii U development and system power. Unfortunately, this pretty good news comes off the heels of some pretty bad news: La Mulana, the retro indie Metroidvania-adventure-platformer that Nicalis intended to publish on WiiWare, has been canceled, though a self-published PC release is still in the works by the developer, and you can still download the original freeware release.

Sword & Sworcery EP, the exploratory indie action adventure with an emphasis on audiovisual style previously only available on iOS, was just released on Steam and is 25% off till April 24.

Privately-held Valve Corporation is tight-lipped about revenues, and Newell doesn't comment on his personal finances. So in order to estimate his net worth, Forbes consulted with video game industry insiders, equity analysts, investment bankers, and technology analysts to figure out what the company is worth. Even the most conservative estimates put Valve's enterprise value at more than $3 billion, and since Newell owns more than 50% of the company, that means he's worth at least $1.5 billion.
