As cool as this would be, I just feel like it would not handle it. at least not long enough for a good gameplay session, lack of cooling would probably destroy the device. Not to mention it'd need at least 4-8GB RAM to support and hold all the stuff because Orbus is open world with minimal load screens. I don't know the minimum requirements for the game so I can't say for sure but I don't think the 2.3Ghz processor could handle all of that very well. You have to keep in mind it still has to run it's phone processes in the background as well so the 4GB or RAM it has is really more like 3 to 2.5GB of free RAM.
But maybe after some further testing and all who knows it might can be polished out enough to be a possibility.
