Here's a double welcome for both TapirUnge and queenofpainting. Nice to have you with us.
The
Scooby Doo mysteries are fun children's games. I think there are five or six, but not all Scooby games belong to this adventure series, so you'll have to pick and choose.
EDIT: If that link above isn't working, just search for "Glowing Bug Man" at Amazon.
Great Journey is a more recent game, and by all accounts a pretty good one.
