I get what you mean with Melee, I played that so much that probably all the hours summed up are at least one entire year, my brother and I would play it a minimum of 2 hours a day per day for the course of 4 years, we were the perfect team, which is odd because we never played team matches, but when our friends came, they knew they had to watch out for us because we were perfectly coordinated and did all sorts of stuff to keep each other alive, and we would juggle them from one side of the screen to the other, it was epic, and then at the end we had our 1 on 1 duel, it was awesome because we were always helping each other but we were also trying to generate an advantage over the other for the final duel, but this being Smash Brothers you never know how it'll finish.
BTW he played Zelda also, and I mean Zelda not Sheik, yeah he changed when necessary but he spent most of all fights as Zelda, I played Marth, Captain Falcon, Ganondorf and Mario, always switching, though really the last year we did our melee match we only chose characters at random.
