(To save reading it all: Got a Wii, didn't like it, bought a 360, loved it.)
I asked for a Nintendo Wii for Christmas, got it with;
Zelda Twilight Princess
Super Monkey Ball: Banana Blitz
HD Component Cable
To be honest, Zelda was my experience playing any Zelda, and I wasn't all that impressed with it. Controls were okay, my arm started to become sore whilst playing which played a small factor to why I chose to sell the Wii.
Super Monkey Ball is good for around 15 minutes, then it becomes boring and quite annoying. Controls are sub-par, usually having to try multiple times to complete a pretty straight-forward level. The component cable, to me, only made a very slight difference in picture quality (42" HD Plasma), and wasn't worth the £27 I spent on it.
To be fair I did have some fun times playing Wii Sports with my friends and close family, and I will end up buying another Wii in a couple of months time for Metroid Prime and Mario.
Selling the Wii, I went out the next day and bought an Xbox 360, and to be blunt, I am absolutely loving this console. It delivers what I wanted that I just wasn't getting from the Wii; Graphics, online gameplay, and games. I bought it with;
Gears of War
Call of Duty 3
To me, every one of those games are absolutely fantastic, especially Viva Pinata. It's a cross between Pokémon and Harvest Moon. Fantastic. Xbox 360 delivers excellent graphics, great online community (I've had many people I've played with in the past inviting me into games of GoW, very friendly strangers), and lastly great games.
I will, however, most likely end up with all three consoles, but for just now, the Xbox 360 defiently does it for me.
