So I know mactheripper is for dvds, but it won't recognize game dvds. I want to rip the game onto my HD, and make a copy of the disc, but it's obviously protected. What program do I need to either decrypt the disc, or allow me to rip the entire dvd?
If it isn't something that Utilities->Disk Utility will do (via New Image), it's likely something that we can't officially condone discussion of here. It's technically piracy, even if you're just making a backup disk, and discussion of piracy how-to is prohibited by the site rules.
Note that I fully believe you're entitled to making backup disks of software you buy... but the government doesn't often agree with that.

It's probably not protected. You're just not using the right program. I have never seen a Mac Game CD that couldn't be easily backed up using Apple Disk Utility.
