Why are you guys giving so much hate towards this guy? I enjoy online gaming. The main reason I like it is because I find it more realistic as your playing against another human who is liable to make mistakes where as the computer, played on a hard setting is not going to make any mistakes whatsoever.
I'll give you an example. If you are playing an online FPS. You have two good players, so it will be a fair match. You both don't know where each other is so you have to be alert at all times. You never know when they will walk round the corner, whether they are camping or running about.
If you was playing the computer, they will know exactly where you are, they have an auto-aim system, lock straight onto your head and they will probably be really dumb and use no thought as to what weapon to use(like use a pump-action shotgun for long ranges). Some games suit online play, but some however do not.
I play battlefield 2 for the PC online. If you play it on singleplayer mode on hard setting you cannot hide because all of the bots know where you are. If you're playing online you can actually hide in bushes, buildings etc as the humans cross-hairs don't just lock on to the nearest person, they have to find them (unless they are cheating, which isn't possible due to battlefield 2's anti-cheat system). If they did find a way around the anti-cheat system they will soon be found out anyway and be banned from the server.
Anyway thats my thought on the matter.
