I personally liked Phantom Hourglass, and I like Spirit Tracks too, but honestly, the Boat/Train really bore me. Then again, the wide open world in Twilight Princess bored me too, however they could have easily fixed that with more action going on in the overworld. If you look at older games, there was a lot more action in the overworld, yet now it is so vast it takes 5 minutes to get between bad guys let alone villages
