Well if your really into FPS's, forget the Wii.
Id go with the Xbox 360 (Newest edition one). Reasons being;
- Live is always up and working. Ive owned a 360 for ages and have never had a problem.
- Yea we have to pay for out DLC but we also get it sooner than PS3 owners.
- The Xbox Live arcade is just insanely awesome.
- Xbox Live Marketplace
- If you finish your games in a timely manner but want more of a challenge, Xbox 360 games have "Achievements" for you to unlock.
- The 360 streams music and videos from your PC.
There's more reasons, but imo, the number one reason would be: The Xbox 360 has a better and huger range of games then any of the other gaming consoles.
