"you have to wait a little" yeah a little. Halo3 is 13 months old right now and are you still waiting for the PC-version?

If I really want a game, I will buy it. I won't wait a year or even longer to buy it. Timed exclusives work, check Bioshock or Rockband2.

If your sister likes the casual games like Scene it, Lips, you are in the movies, the PC won't help at all.

If she likes games like Halo3, Gears of War2, Fable, the PC won't help.

If she likes Banjo or Viva Pinata, the PC won't help.

If she likes JRPGs like Tales of Vesperia, Last Remnant, Infinite Undiscovery, Lost Odyssey or Star Ocean, the PC won't help.

If she likes Racing games like PGR4 or Forza Motosports2, the PC won't help.

If she likes Arcade games like Braid, Castle Crashers or uno (playing it from a couch with Headset and camera) the PC won't help that much.

In a word: The Xbox360 has a good lineup of established exclusives that won't be released on the PC. Don't listen to those haters saying, every Xbox game will be released on the PC as well. And the NXE might be perfect for your sister.

And you can play everyone of those games with the purchase of a $200 machine.

^ Viva Pinata is on the PC,

The 360 is a good investment. The PC is also very useful but it wont get Microsofts most important console exclusives. Theres a reason MS didn't throw PC a bone with Halo 3, Gears 2, Fable 2 and more. Last year with the non exclusivity Microsoft made a big mistake and now they are covering their tracks.

If you want the games played in the living room, why not?

Although you could set up a PC with an HDTV, the PC isn't *usually* the centerpiece of a living room. Get a console for that. A PC isn't a complete replacement of any console, no matter how powerful it is.

PCs are "do all you can" machines. Consoles, on the other hand, are easy to pick up and play (a quick play of Soul Calibur for instance).

Besides, you don't want to interrupt your sister's IM session when you drop by and want to play Gears or Halo or something.

seeing as how she already has a PC and a HD console, have you considered getting her a Wii instead?

The games on PS360 are getting more similar by the day it seems. If she had a Wii that might provide a bit more variety?

I think what she really needs is a good pair of shoes and a soccer ball to get her to go outside if she needs that many gaming consoles.

Braid is such an amazing game...

I'm not sure about what games are exclusive to the 360 and not on the PC, but a different factor is whether or not you have friends who play on Xbox Live, and whether you'd want to play on it.

Gears 2 alone would be worth paying £300 for a 360. So yes.

Couldnt care less. I have Gears 2.
