I picked up Fable II today, and I will get to playing it as soon as my wife is done with the TV. In the meantime, I figured I would discuss a little bit about my personal opinion on the Xbox 360 vs. the PC as a gaming platform. Everyone has their own point of view about this, but this is mostly for the benefit of my friends that play videogames, but don't currently own a 360.
I work all day in front of a PC. So when I want to relax, I don't really want to be in front of a PC anymore. My desk chair isn't all that comfortable, and when I'm sitting in front of a keyboard, it just reminds me of more work. When I play on my 360, I'm on a comfy sofa. There is no email anywhere nearby, and it's a much more relaxed setting.
Also, things are EASIER on the 360 when compared to a PC. If I have a new game I want to play, I put it in the tray and go. I don't have to install the game, type a key, update my video drivers, reboot, or anything like that. I don't have to worry about DRM installing wierd crap on my machine, either. Again, it just feels a lot less like work.
There is also the whole Xbox Live aspect of it too. A Gold membership costs something like $60 a YEAR, which lets you play online against other people, tracks your game stats, etc. The money is very much worth it, because the online matchmaking service is very good, stable and fast. XBox Live also tracks in-game "Achievements", which is basically just for bragging rights, or gamers would want to absolutely, positively complete everything that there is to do in a single game. Some achievements are quite funny, such as this one in Fable II:
"The Chicken Kicker: Kick a chicken a good distance, or see one getting kicked."
I guarantee you'll see that one on my gamercard as soon as possible.
