I finished episode 5 yesterday, and thought I'd post on my thoughts after finishing the season.
First, the bad:
1) No universal settings like S&M season two. I'd like to be able to set my resolution and whatnot just once and then play the remaining episodes on those same settings. I also would've liked to have some kind of "advanced" panel for setting FSAA and AF, as I've spent quite a few euros on my desktop and think it's a bit silly to have to fiddle around in nVidia's control panel just for Telltale's games.
2) Some hassles with the controls. The worst was upstairs in Strong Bad's house, it was sometimes a bit of a trouble to move from room to room, because SB would sometimes start going in the wrong direction or wouldn't do anything at all if the cursor wasn't exactly where it was supposed to be in the adjacent room.
3) Sound quality. Didn't bother me as much as S&M seasons one & two, but still, definitely needs improvement.
4) Maybe a bit too much time was spent in the same environments doing the same things. Especially the metal detector became a chore as the season progressed.
1) Hint system worked really well and seemed to always know when to throw me a bone.
2) While the writing didn't really make me burst out in laughter more than once or twice, it kept a smile on my face. I especially enjoyed all the retro-game goodness in Episode 5, and my second favourite was Baddest of the Bands.
3) I'm not a huge fan of Homestar Runner, but I do enjoy the occasional SBEmail. I'm glad that the writing didn't seem too fan-servicey (in that even a non-fan was able to enjoy it) and I think the season did a good job in introducing many of these characters.
All in all, I enjoyed the season all the way through, even if did at times feel a bit repetitive (a problem shared by both seasons of S&M). I hope we'll see the universal settings from S&M season 2 in Telltale's other/future games and I'm also hoping for improved audio quality in the future.
