Quite an Old thread with no reply at all, so I try.
First of all let me state, I came to 'Alive' just a few weeks ago.
I personally like 'Inner Tube' best of all the included games and environments.
I am working as child psychotherapist in Germany, and in my practice children (mostly aged 8-16) like 'Dual Drive' and 'Advanced Media Player' most.
To the point of the topic:
The idea of implementing biofeedback into regular games is great. I think it will be very exciting playing 'Half Life' in Bio Mode.
Quite a problem HL is rated 18 in Germany, so I could not offer it in my practice.
My suggestions Out of my experience with my young patients:
Many of the kids like StarWars, I am sure a Game like SW The Force Unleashed could well be a similar to HL but adequate for younger kids, in Germany the Force unleashed is rated12.
As many of the kids like Dual Drive I also think a commercial title like Need for Speed will be of interest too.
Finally let me add I would appreciate any upgrade / addon for Inner Tube as well as Dual Drive.
Hope to give a New fresh impulse
Greetings from Germany, Armin.
