I personally feel that the only system I have seen so far with a reasonable rate of success is dedicated servers with some sort of permaban of accounts caught cheating. While by no means a perfect system; my personal experience (with TF2 as that is the only FPS game besides MW2 I have played over the last few years) was that I found a gaming site that ran servers for a variety of games. An extended group of people frequented those servers, creating a community of sorts, and I personally never had much problems with cheaters (that I can recall). Either they were banned/kicked swiftly and effectively, or they never logged on that particular set of servers; or possible a combination of the two. Though it should be mentioned that over the last two weeks, or so, of playing Modern Warfare 2 I haven't really seen a lot of players that I could confidently claim were cheating; though I have seen a few that were ridiculously good. Perhaps that is just me not really paying attention.

Cheating or no cheating, sales or no sales, I personally feel that despite Modern Warfare 2 being a really great game at its core, I won't be playing much more than I have; as it really feels impersonal when all the other players are random. And there is no forum for me to hang around talking some trash between matches and evenings. This of course isn't helped by the fact that Iwnet seem to have about a 30% (number I pulled out of my behind but it is how I have experienced it so far) failrate; disconnects, game closings, kicked from a lobby before you have connected to it, random ping, and people leaving games because a map comes up that they don't want to play (Highrise and Estate seem to see half the "group" leave when they come into rotation) leading to lobby's closing most of the time.

Well, it all started in 1962... Utilizing advances in modern food synthesis, scientists at NASA began work on a germ hostile space meat to be used into long expeditions in deep space! Only recently has their hard work paid off. As even more advances in the field of space meat have been made and applied to what is now known as operation meat. Seeing this as a way to end their streak of being sued by angry costumers poisoned by their burgers, the Mac Meaties corporation decided to try this miraculous space meat. Not having access to that technology, we make ours out of napkins.

Just wait til you find out how this 'internet' thing works!

It depends on the OS in question, and the differences to the previous version, and if they're significant enough to warrant parting with your cash.

The same as buying a new anything, really.

How big are YOUR hands then?
Mine are only large enough to hold one, perhaps two boards at a time
