1. I have yet to see a Wii game look worse than the GameCube - Red Steel included. Don;t believe the hype. Red Steel does not look bad, at all.
Videos and screenshots I've seen show low poly characters and environments, average textures with nasty baked in lighting, unconvincing animations - it really doesn't seem to look as good as the best looking games on the Cube.
2. It's well worth the price. I'm sure just about everyone here will agree with me.
It depends on what you're comparing the price to - nearly 200 quid is a non trivial amount of money for something that doesn't do a lot more than the Cube or PS/2 and (controller aside, which is not an unambiguous plus point) does a whole lot less than the 360 (which is dropping in price towards the point where the Wii is looking far from a bargin)
3. Super Monkey Ball controls just fine. Any complaints are coming from people who either haven't spent enough time with the game to properly master the tilt controls or who are too stubborn to learn.
I've heard people complaining it gives them sore wrists because the neutral position requires holding the controller at an uncomfortable angle - we'll have to wait and see if this is a common problem or not, I guess.
4. I'm not much of a Zelda fan (though I did buy "Twilight Princess") and the other 4 games I bought are as different than Zelda as can be. I'm completely satisfied with the launch line-up. Honestly, what system has ever launched with a robust library? None.
Maybe I'm just going off gaming but I just can't get excited about any Wii launch titles - what 4 games did you get?
5. Any network issues will be worked out by Nintendo. It's hard to roll-out a new service and hiccups are to be expected. Updating issues only apply to the units assembled early on and for whatever reason hadn't had their firmware updated at the factory. Nintendo is replacing those with brand-new Wiis.
Brand new Wii's from the Japanese and European allocations no doubt - I'm not sure I'm happy about that
6. It's not widespread and surface scratches are common. Disc-based media are delicate and no matter how careful you are while handling a disc, scratches are going to happen.
I think they'd have been less likely with a more conventional (and cheaper) drive, but again I guess we'll just have to wait for the dust to settle and see how common this problem is.
