Yup. All the old Lucas Arts adventure games were great and it's really easy to play them now on new hardware using ScummVM. You tried turning on any of the graphics filters? Some people like the old school blocky look still tho

I've got a SE P900 phone and there is a port of ScummVM for it. Really eats the battery however.

Beneath A Steel Sky and Flight of the Amazon Queen were both released as freeware by the original developers and are supported by ScummVM as well.
