Look at the games you want for each system, and whichever has more that you want to play choose that one. Both the 360 and PS3 are pretty much neck and neck in terms of benefits, and in terms of cons.
I would also advise looking at what console your friends have.
Its always more fun playing with a friend, then a faceless online player. Atleast for me.
its down to the 360 and the ps3
You have looked at the games you want, right?
Just don't get a Wii.
I have a wii for like a year now and i havent bought a single game for it yet.
there is nothing good on it, it has no games, same old rehash you played on the game cube like mario galaxy and smash bros with some updates and gimmick gameplay.
i looked for innovation on the wii not game cube games.
Ill start looking at the games in the morning....
the nice thing about ps3 is that u don't really have to buy any peripherals for it. it already works with most usb/bluetooth headsets, keyboards, and mice.
Read up on all of the products you are interested in and make a decision for yourself. Closing this pointless thread.
