I am looking at offers for my Steam account, no bans, no VAC issues. I am the original owner and you gets what you sees. There are 340 games on the account, with most major releases (Shadows of Mordor, Bioshock Infinite, Skyrim, etc.). The account value is $3200, looking to get about $3000 or best offer.
Why so expensive? Because you get an original account. Most accounts here with 300+ games for <$200 are stolen or hacked accounts, often with VAC and account restrictions. I can verify I am the original owner, providing last 4 CC digits, PayPal, drivers license, etc. to confirm.
