The Radiant website announces the developer has been acquired by Riot Games, saying they will continue development of Stonehearth, but that the alpha for fighting game Rising Thunder will close later this month (thanks GamesIndustry.biz). The implication is that they may be creating a similar project for the League of Legends developer and publisher. Here's word:

We are delighted to announce that Radiant Entertainment has been acquired by Riot Games. At Riot, our developers will continue their mission of building incredible games that speak to us personally as players. You’re probably wondering what this means for our games.

First and foremost, Stonehearth will go on, full speed ahead. We’ll continue delivering Alphas at our current pace, with the aim of delivering the final game “when it’s ready.” We’ll continue keeping you up to date on our progress through things like our Twitch streams and Desktop Tuesday blog posts.

As for Rising Thunder, the team will start work on a new game that we’re incredibly excited about. We wish we could say more now, but rest assured you’ll hear more when the time is right. For now, we will be permanently closing Rising Thunder on March 18th. Thanks to everyone who participated in the Alpha!

And more broadly, to everyone who has helped support us by playing Stonehearth and Rising Thunder, backing our Kickstarter, telling your friends, and giving us your feedback: Thank you for helping us make these games as good as they can be. You have been a consistent source of motivation and inspiration for us, and we look forward to continuing to talk and work with you in the future.
