Hmmm.
I've never specifically done a project of playing straight through a series, one after the other.
However, if you allow the concept of playing one game multiple times, then moving on to the next, playing that a bajillion times, etc., I pretty much did that for my Space Quest Many Deaths of Roger Wilco website. :P
Also, I played straight through the Gabriel Knight series when I first played the games, however I have yet to get around to re-playing them. (And in fact, as much as I'd like to, I can't re-play GK2 on my current configuration... at least, not without going insane.)
At some point I really should re-play the Monkey Island series, though. :)
Peace & Luv, Liz
I did that with the Monkey Island Series ;D, i played the first one on my new computer and the second one on my old computer ;B, i was playing both at the sametime so i got the puzzles messed up as well XD
Ahh, the joys of owning nothing more advanced than a mere Windows 98...
And if I ever have any problems playing really old games on that, I can use my old 3.1!
Does The Elder Scrolls count?
*trys to find a way, to get Space Ace working in XP*
Ive played through QFG repeatedly from 1 to 5... Trust me, a 5-game-strong Paladin is absolutely unstoppable! 8)
Oddly, there's a way to export characters from Daggerfall to Morrowind(odd, because the company says you can't 8) ).
