TLJ Disclaimer: There is one ridiculously long uninteractive dialog exposition... thing sort of near the beginning of the game. Other than that, the game's not too overly wordy, but just be forewarned. ;)

If LucasArts comes to GOG I will buy everything single game for myself and then host a massive giveaway. Assuming I have money. Which I, uh, probably won't. >.>

I have no problem whatsoever with lots of dialogue...as an English major, I appreciate it, haha.

I absolutely loved the two Syberia games, and they fit this description perfectly. The Longest Journey is also fantastic, but does have a few weird puzzles.

I don't think I saw this one specifically mentioned: Indiana Jones and the Fate of Atlantis. It's a really good adventure game that I just played recently (it's on Steam) and was surprised to find that it was even fully voiced. There's even a choice you can make to determine how the majority of the game plays out, either:
1. Emphasis on fighting rather than puzzles
2. Simpler puzzles that are solved with the help of a partner (a woman who joins you on your quest)
3. Difficult puzzles and you go through it alone
