Just readed an interview about Outerra on battle.no, very intresting, its designed for the pc in mind and you need a dual core with a GTX 460 to get it smooth (in the future a 8800GT would do the job too). To clarify, its an engine, that will be used for simulation, but they have a game in mind aswell. You can read here, its in English http://battle.no/?section=news&nid=606
Reminds me of Flight Simulator X. Or more correctly it reminds me of false promises and lies of Flight Simulator X.
Flight Simulator were a nice series, used to 'play' them alot. Maybe we will see FS back with this engine, would be cool.
