Selling steam account with Batman Arkham Knight

Hello, i'm here to sell my steam account due to some minor problems with Batman Arkham Knight (don't have a good enough pc to play it) and i'm looking to sell most of my pc stuff.

This account includes 58 games, and some DLC, for example for BO2, Arkham Origins. All in all, the games on this account is valued at 687 usd (not counting Batman Arkham Knight).

All games on this account:

Value of this account:

Even tho' its worth 727 i only want 70% of that so 508 usd.
Buyer goes first in my trades.
