depends where you get it from but GAME do i know
It is free at the xbox live arcade
About two differences: one: the xbox three sixty has a harddrive two: the xbox arcade comes with free arcade games but doesnt have a hard drive
an xbox 360 arcade only has a memory card free but the xbox pro has a 60gb HDD.
No, there isn't a free trial.
No but it has a free one month gold trial that comes when you hook up live but then you have to pay.
To download arcade games you need xbox live, but all you need is a silver membership which is free.
Go to Xbox Live Arcade, click on a game, and download the free demo.
Only the trial version.
Xbox arcade games have a free trial but do not provide achievements. I have not come across a free arcade game with achievements. However, you can download the game arcade room which is free and have achievements.
The Xbox 360 Pro Bundle comes with a hard drive(20 Gigabytes originally but these days a 60 GB) and a chrome disk drive cover, with other accessories like a headset, Control Remote, Wireless Controller. The Xbox 360 Arcade doesn't come with a hard drive and has a white disk drive cover, no headset, wired controller, no control remote, but it has arcade games with it for example sonic the hedgehog, pacman etc. If you get the Pro Bundle you can hook up to xbox live and download the arcade games off the Xbox live marketplace and play them when ever you wan you also get one free arcade game and several trial games as well as some of the latest videos on the latest games available.
im not sure but i belive it is 1 free month of xbox live
yes it doesnt matter if its an arcade version or any of the others, the arcade games will still be able to be downloaded as long as you have enough free space on your hard drive or mem card.
