Picked this up some time ago but then have switched to console gaming.
Seal is in tact all around so there shouldn't be any issues with the Steam key - though, of course, I can't open it to check. Apologies for the angle on the pictures - reflections were getting in the way otherwise.
You don't generally need to install the game from the discs but I'd imagine anyone buying this wants it for the physical media as Steam keys of the game will be much cheaper elsewhere.
All my items are stored in a pet and smoke free home and I have excellent feedback rating.
I'll always try to be the lowest like for like price on ebay - unless I feel the item quality is substantially above the cheapest - but am open to sensible offers.
Items are typically posted 2nd class large letter unless the value is over £20 where tracked will be used.
