I hope there is cos they could be a alternative thing insted of via domus (the way home) they could have a timeline that he doesnt go of the island and that follows through seasons 1-2-3-4-5-6! and i then could include this like
1. Dharma stations
1a. Dharma Barracks
1b. The people from the tail section of the plane and you could change the story-line!
1c. And also! they could have a thing where you get of the island and you do missions off the island and then ti could guide you back
1d. Charles widmore's boat!
1e.
OR They could have a story line that you are one of the others!!!!!!!!!!

THAT WOULD BE AMAZING!
I would definatly buy it! any of those storylines
and any other lost fans would as well I know it!
