How do you pick future projects? Are you contetrating on Sierra for now or are all old Windows adventures ok?
I have a couple of title suggestions for you to look at if you have the will and the time:
1. Black Dahlia: this great FMV game seems to work in modern Windows but the controls are waaay too fast, modern processors even seem to crash some puzzles because of the speed. I guess it would perhaps be easier than Sierra titles since it already manages to run in 32bit OS-es.
2. The X-Files. The only problem this game seems to have is using the old QuickTIme 4 format. Could you do to it what you did to Amber (which also used quicktime I think). The funny thing is that it wouldn't run in Vista, but it did in Ubuntu under Wine.
3. Morpheus: A great adventure game utilizing QuickTime Movies and VR. Also circa QuickTime 4 era, similar to above.
If you fix theese games by recoding the videos I'll gladly donate my processors time to do it.

As far as Sierra games go, Phantasmagoria I and Kings Quest VII should be right in your present area of interest.

So once again congratulations and a big thank you. Looking forward to future games (whatever they may be).
