Ok Boys and Girls, seeing as i am 18, and possess a fluffy mustache - I Know Better, so here is My Opinion.
This Console in my opinion is made for one purpose; Social Gaming.
Since its release, its primary function is to provide a Platform for Gamers to come together and berate each-other with 'yo muma' jokes and have mass arguments about Global Politics and whatnot, the Xbox Community is a fascinating one, a million strangers casually talking to each other, its a great place to talk, argue or even wind-up people seeing as no two conversations are the same.
The use of the 'Party' System allows a group of us to chat casually whatever where doing. which is useful when a group wants to play a War Game, whereas the others want to play some Fifa.
Now the Xbox Experience is genuinely unique, the use of highly customizable Avatars who are now becoming a part of the gaming experience (Guitar Hero 5/1vs100) it allows players to immerse themselves within the usage of the Xbox, making them want to use it more, and these features do work. The 360 is also great for trying out games before buying and it is a money-saver for your wallet, you'd rather find out what a game is like before buying it, rather then buying the damn thing, and realizing its Garbage (Blacksite for example ha).
Now i have one forward complaint about the Xbox which i think a majority of owners have noticed and questioned - why in the name of god does this thing churn out more Heat then an Oven?? this can really ruin your gaming experience primarily because you don't want to play a game when your room is the same temperature as Morocco. haha
Now i didn't want to get into The Xbox vs. PS3 War, but to avoid being dreadfully brandished a 'Fanboy'. i will say both possess Key Features the others don't, but this doesn't make either worse, it just makes them 'Envious of Each Other'. Now my Xbox has Died Twice, but has been repaired properly but it has been made quite badly compared to the Playstation, My Elite barely a week out of the Box, a Warm Breeze comes through the Window, and BLAM! Red Ring of Inevitable Doom..... The Playstation, Bought Second Hand from a questionable Gentlemen was doused in Beer and left on for a day straight; Keeps on working... the only downside is it now smells of Stella Artois....
Now Xbox Live is where xbox absolutely spanks PS3's Behind, primarily because there are People PLaying and Talking! The xbox just seems to be more accessible for people, they are more willing to play aggressively and have a laugh with you, Playstation Online is only met with a eery silence of Mute Players.....
Overall, if you want a Console which can provide you with endless hours of fun with a abundance of Games which you can enjoy with a community bursting with inane Banter - Buy Yourself an Xbox. :)
Cheers for reading guys.
