there are a lot of games that are region free,most games by ubisoft,atari and some ea games are region free. the games that are region free were produced like that,a good place to about pecific regions of games is play asia. when you say have these been made region-free or produced like that,how do you mean? publishers have the choice if they want to region-lock their games or not.thing is some games will only work on a japanese nstc 360 but yet the asiannstc version could run region free. play asia is your best bet.im sure their is probably a list out there.
