I realized something. King's Quest has been MIA for a long time, and this new game will probably be a lot of people's first encounter with the series. I think once this game draws closer, Telltale should do something to help familiarize any newbies with the world of KQ. Two thoughts...
1. They could sell the King's Quest Collection on the Telltale Store, just like how they sell Secret of Monkey Island Special Edition. Maybe even give it free/discounted when you pre-order the new game. I know they sell the Collection on Steam too, so maybe a "King's Quest Bundle" is possible?
2. This is a bit of a stretch, but maybe actually include the older games with the episodes? I doubt they'd take up too much memory.
What do you think?
