I will do however many games you want but, the more you want, the more I will charge. I will not do Forza 2, Call of Duty 4, and Call of Duty 2 in one go. They take too long so I am only willing to do 1 of those games at a time. (Unless I like your price)
Feel free to send me a message on Xbox Live (GT: S3riosly Glitch)

There is no set price. Just make an offer with the list of games you want done.
