Early Access titles are slowly but surely starting to take over Steam's list of top sellers. Following the prolific DayZ Standalone alpha joining Early Access yesterday, another game that's been kicking around for a while now, Overgrowth, has been added today. On Steam, it's slightly cheaper, coming in at $24.95 vs. the Humble Store offer of $29.99 (which also includes a Steam key, and access to Wolfire Games' Receiver and Low Light Combat).
Wolfire also has a put out a helpful video explaining what Overgrowth is beyond "that fighting game with the anthropomorphic animals." It is that, yes -- but it's also so much more. Combat is context-sensitive and technical in ways that screenshots can't do justice.
It's exactly the kind of game I'm terrible at, but I have a substantial amount of respect all the same.
