well... you did mention Monkey island and Broken sword, so I thought you might like "that ancient game" !
Actually there are 3 legend of Kyrandia games. But to be honest I only played the first (and with voice, the cd version)
But if you do like jungle I do recomend Return to mysterious island and Destination-Treasure island. It gets a little use to the 360 degree system but the scenes are gorgeous!
And if you want a modern 3d third person jungle I'll go with the rest and say So blonde and Jolly Rover best, and there are some jungle scenaries in Secret files 2 Puritas cordis that I like too.
