Well its a scam and not a scam. Its both! lol

Let me break it down for you.

If you have an Un-Modded Xbox this site is useless for you. You wont be able to use anything.

If you decide to Mod your Xbox you should be able to use this site to get free games and what not. However this comes with three problems. the first is that you will never be able to play online again. A modded Xbox can not use Xbox live or it will be banned and a chance that it will be bricked(in other words it will never turn on again.) If you don't know how to mod a xbox chances are you may break it before you even manage to mod it anyways. The third is then it is still a scam because if you simply look other places for games you will find the downloads for free other places.

The last option is if you already have a modded xbox you should know you can find the games other places for free.

This site is a scam in the sense that it works but its making you pay for something that you can find for free elsewhere.
