It kinda lost what made SQ great for me. The feeling you were part of a bigger universe, kinda like star wars. SQ3 still captured the atmosphere best for me. Had your spacespace and you could zip off to explore different planets.
The super highway jokes were old back even then, and the inner body thing.... agh.
The game grumps playthrough of SQ4 is a bit more happy.
Anyone else have good SQ playthroughs with commentary?

Being critical of games is really their whole style, however they were negative of many LucasArts games as well (apart from Loom).
As someone who loves sq3 the most, I did enjoy the nickpicking.
Yahtzee (of Zero Punctuation fame) does a pretty funny let's play of SQ3 with commentary about old adventure games.

Edit: They are rather critical.
Also worth checking out the Game Grumps play through of SQ4.
