I played
All of them up until about Out Run which was about the age I left school and became "responsible". I too remember Dragon's Lair and remember being blown away by how good the graphics were. How much was that game, a pound or something? I remember it being prohibitively expensive though when everything else was ten pence, even 20 was expensive back then!
Handheld incarnations of DL are a great idea and will want to buy one for my PSP when I've read a review or six.
