if ur in the US or can afford orig games specially if u have DSL (ora ny broadband connection at home) and relatives in the US u can use XBOX LIVE for online multiplayer gaming
if ur in the phillipines with a tight budget, no DSL at home(using dial up) and dnt have relative in the US, ur best option is to buy a modded one
since a modded 360 that cant be used on xbox live service is just like ur old modded ps2 that u can use on ur own or with friends at home and CANNOT play online games
