I like the idea of a hybrid.

The original plan was to use the acceleromoter and simply 'tip' the sheep into the pens (like those old games with ball-bearings). I'm reluctant to lose that idea: part of me knows that as a non-gamer, that's something very accessible to people like me. It is also useful for developing delicate sensory-motor skills, whereas conventional games are good for developing fast reaction times.

Could a hybrid use different forms of input, different ways to chase/pen your sheep, in different levels? So the first task of each level would be to work out how to chase your sheep? Then the maemo4 version of the game would simply leave out the accelerometer levels. If say, level 1 and level 4 were dependent on tipping the device, level 2 used a dog to round up your sheep level 3 did something different again... each time with more sheep...

Am I getting too complex here?

(Oh, and I'm working out how to get some random 'baas' recorded.)
