When I first picked up the bundle (and bought one for my friend), I thought Lugaru was the weakest-looking of the bunch. But so far, it's the only one I've been playing with any sort of regularity - it's got a bit of depth to it once you get into it, especially once you start coming up against wolves: approach from upwind; don't have blood on your weapon (they can smell it a mile off); etc
The biggest hassle I can see porting it to the Pandora (apart from technical issues like x86 -> ARM) is implementing a control system that 'works'. It uses a lot of WASD + Mouse + Mouse Left Click + Left Shift + Space + (to a lesser extent) Q + E, and uses them in a very fast-paced and crucial-to-be-able-to-get-to-them-instantly sort of way. I can see the shoulder buttons getting a good workout, as one will need to have a thumb on the two nubs (or right-nub and d-pad) at all times, which limits the usefulness of the ABXY buttons.
One day maybe we can all be a part of the rigorous beta testing to get the controls right.
