Here, I'll start. When I was 8 years old, my parents went to a dinner party and plonked me down in front of the host's computer so I'd stay out of their way. The game they booted up to keep me occupied was Space Quest II. Little did they know what impact that would have on me...
Aaah I remember this game! I think my cousin played it, but I was still too young. The first adventure game that really got me hooked was King's Quest 7. It had voice over in my language. Sadly, the game is not compatible with modern PCs anymore. And GoG only has the English voices. I would like to play it in German again, for the nostalgia.
