The Monkey Island remakes destroyed the original art style. I like the more cautious path they took for Day of the Tentacle.
It was certainly different, but I wouldn't say the original art style was 'destroyed' due to the fact the at any time in the game you can switch back to the original style. It's not exactly destroyed if its RIGHT THERE.
I think with DotT there is less room for that kind of art upheaval though, because, frankly, the art already looks good. It still holds up very well today, expecially if you run in SCUMMVM in turn on some graphics filters.
I still wish the graphics were better, it looks like Grim Fandango and Day of the Tentacle don't have much improvement in graphics department, so I'm afraid Full Throttle will be similar disappointment to me.
Comparing that to remakes of Secret of the Monkey Island[1] or Bionic Commando Rearmed[2] (different genre) it looks poor. It feels like LucasArt (and actually Disney) are simply going for making easy money on people who are nostalgic about these games with as little investment as they can.
