Obsidian revealed on Saturday that the mysterious RPG it teased last week is a new IP by the name of Project Eternity, and that it was seeking US$1.1m (AU$1.04m) on Kickstarter to get it made.

Fewer than 48 hours later, Project Eternity had crossed that Kickstarter goal, and currently sits at US$1,343,797 (AU$1,272,941) from 34,369 backers with 30 days remaining.

According to Obsidian, the isometric party-based RPG is “an old-school styled CRPG for the PC, reminiscent of the Infinity Engine games”.

“Project Eternity will take the central hero, memorable companions and the epic exploration of Baldur’s Gate, add in the fun, intense combat and dungeon diving of Icewind Dale, and tie it all together with the emotional writing and mature thematic exploration of Planescape: Torment.”

The game is the eighth to cross a million dollars on Kickstarter this year.

“We've hit our goal quicker than anyone expected, and the last day has been overwhelming,” said Obsidian.

Stretch goals include a new races and classes, Mac and Linux versions of the game, and new regions and factions.

Obsidian is looking into making the game DRM free.
