Im probably going to say from back then:
"
Sonic Heroes"- Back then, I was doing good for all the teams, but some stages made me furious, it took awhile. Then less than 2 years, I was able to get all A Ranks for each team and unlock Super Hard. Yes, that got me upset for not beating it all yet.
"
Mario Sunshine"- When I began to play this, I actually did a good start, and did great at beating it. But some parts, as usual, were getting on my nerves that i had to repeat a lot of stages and episodes. But once I mastered it, it was perfect, and I beat the game 5 times.
"
Majora's Mask"- Oh man, was this a hard one. When I first played Majora's Mask, one thing...a Whole New World. Once the beginning events at the Clock Tower began, I was completely lost, and didnt know how to find the first temple. Very detailed game. But later in 2004, I bought the game at Gamestop, and the game was already complete!
So I did it again, and beat the boss where the game left off at the Clock Tower. I faced the final boss, and he was mine! Game beaten just like that.
And theres a few more, but Ill post them later.
