I've had some playtime with the Wii now, enough to give it a fair evaluation, and I think if they don't make some extremely high quality, call-out-of-work-to-play-this-game level material, the Wii is going to totally fizzle out. Some of the more recent games, such as Wario Ware (pictured)and Elebits are fun for a short while, but the heart of the game is just exploiting the Wii hardware for what it can do. Wii Play has been called a Wiimote with a tech demo packaged along with it, and I have to agree. Think of the Wii as the hot chick you spot at some social event. She's elusive and hard to find, and when you do work up the nerve to talk to her, after 20 minutes you realize she's a complete moron. She functions, can hold a conversation, and makes a good first impression, but when it comes time to talk about important things, she just doesn't show up.
So how do I score the "next gen" as of now?
Wii - Fine for casual play, but not serious gamers. Hopefully Mario Galaxy and Metroid Prime 3 will change my opinion a bit.
360 - Still in Beta testing. Seriously Microsoft, we don't want to rent a console for $400 for a one year term. Know why they call it a 360? Because that's it's shelf life before it dies on you.
PS3 - I honestly think Sony is TRYING to fail with this thing. Just today I read that Europe is getting a downgraded ps2 compatibility system. The list of Sony screwups keeps getting longer and longer......
My solution? Enjoy the ps2 for now, and the great library it has to offer. Four words for you if you disagree: God of War 2.
