Hi!
You could do worse than take a look at the 2000, or so, featured on my little old website. I've had persmission to mention it here before, so don't worry. I think a couple of people here have actually joined the forums there too.
Anyway, you're more than welcome to take a look.
It's here . . . . . . . . .

I could talk about point & click Adventures for hours on end, but I would only bore you to death. Best just take a look and take some time to browse the illustrated database.
