I, as well as most others here, will HIGHLY recommend Tales Of Symphonia. Final Fantasy Crystal Chronicles was a steaming pile of chicken vomit compared to Tales Of Symphonia. If ToS and I had children together, I'm pretty sure they would be the next benevolent rulers of east Asia. All twenty seven of them.
Seriously, GET TALES OF SYMPHONIA. I cannot even tell you how good it is. The plot is fantastic, the characterization will blow you away, and there are HOURS AND HOURS of gameplay. It's not uncommon to go STRAIGHT THROUGH the game with little to no deviation, following only the main plotline as straightforwardly as you can, skipping ALL dialogs, (A speed run, basically.) and finish with 30 hours or so on the clock. I had about 70 hours on my first run through after bumbling about, doing everything I could find.
SSBM is an obvious choice. Use it, Learn it, Master it. Then when Smash goes online, I would like to face you. That goes for anyone and everyone. It's the one game I would ever even consider boasting openly about, actually being sure of my ability, and having had proven myself time and time again. ... ... Okay, I'm done.
How is Animal Crossing, anyway? I'm looking for a little nightly entertainment. Is it at all like the Sims? Just a little leisurely stroll through a gaming experience at night that won't make your adrenaline rush. I would very much like to check it out.
The Wind Waker is ABSOLUTELY a good choice. If graphics are a put off, I really, really wouldn't know why they would. They're just so detailed! The animation is smoother than anything I've ever seen before! It looks a little cartoony, but once you get past that "Flaw," if it is one, the game just looks gorgeous if you can get your head out of your arse. Sailing is only bad if you have a fuse of patience the size of your own male bits. You don't have tiny male bits, do you? (I'm pretty sure someone won an election with a line like that.)
Both Metroid Primes are an excellent pick. Some would call them difficult, but they're not truly that difficult. You just have to be tenacious and observant at all times. Monsters have a lot more hit points than many would care for them to have.
Soul Calibur II is fun. Can't really say that much more than that, I guess. Blocking, unlock most other fighters, is actually fairly effective, thank god. It's not nearly as efficient as SSBM's block, but it's a HELL of a lot better than Mortal Kombat's block. You even have direct control over the parry and deflect features. SOOO USEFUL.
Bloody Roar Primal Fury is pretty nice, I guess. The concept is interesting, and works well with what you get. Some of the characters are really unique as well. Uriko Nonomura is a hottie. ^.^ Ehehe. XD Rent it before you decide to buy it, but do stick with it for the whole trial duration. It has high replay value, and others play it religiously as well, and you shouldn't find yourself without it when you need it.
My sister has a Harry Potter: Quidditch game on the 'cube. It's not bad, really. Like any other sports game, it'll have you yelling at the TV, trying to get at that quaffle thingy to throw into one of the three hoops. Do rent it before you decide to buy it though.
