Anyone ever noticed that Zelda: Wind Waker (And Phantom Hourglass) has a lot of parallels with the Monkey Island series? :D Off the top of my head;
-The entire world seems to be made up of an endless ocean with various gimmicky islands, and it is populated by pirates who are never seen doing anything particularly dangerous.
-The main character (Link/Guybrush) is a clumsy blonde guy who seems to be the only one aware of how bizarre and silly everyone around him is, and picks up extremely good swordfighting skills in a very short amount of time.
-The main character has a talking boat at one point (King of Red Lions/The Dainty Lady) who turns out to be more important than they initially appear.
-The main character's female companion (Tetra/Elaine) is loved and respected by everyone, and tends to have a bit of a temper. She is also very capable of looking after herself, yet also gets kidnapped later on.
-Anachronisms everywhere; Wind Waker has cameras, Monkey Island has...well, mostly everything.
-The crewmates either disrespect the hero (Most of Tetra's pirates, Linebeck/Guybrush's crews in Secret and Curse) or idolize him (Niko/Winslow)
-The hero is repeatedly fired out of a cannon, much to his discomfort.
-The villain keeps coming back and just won't die ever, and usually when he returns it's in a new form. (Ganon/LeChuck)
-Erm...there is a character named Tetra?
-And one from Ocarina of Time instead of Wind Waker: The hero is hit on by a fishlike merperson (Ruto the Zora/Anemone the Vaycalian) and does not enjoy it at all.
I'd have to say the similarities became more obvious when Tales came out, being a 3D game with a gorgeous cartooney art style. ;)
