I know nothing about mods. Is there any risk involved? (corrupted game file, hurting the console, etc...)
Also are they free for people to use or would I have to pay for them?
there is no risk involved unless you have a slow computer and you install a high def mod will make it run slow, also if you get a mod off a youtube vid make sure you see the like and dislike count. but i am gonna put my mods on the ps3 gta 4 when i buy my knew one and the x3max usb. and yeah they should all be free.
