> That's not really an issue to be concerned about I don't think. Any game can be changed/hacked, even the most successful ones are (minecraft, skyrim etc.).
Neither of the games require hacking to change those, they allow users to mod. You don't see a ton of Mass Effect mods or changes, because they are harder to change.
Or maybe it takes a lot more effort to produce the content. Making a 8 bit texture for some cube man is a lot different than sculpting a normal map, and tweaking a bunch of shaders for a next gen game.
EA does nothing to stop or hinder Mass effects mods.
