It was the lan yesterday, and I had decided that it would be nice to play Modern Warfare 2. As I am pretty cheap I saw a copy on Amazon marketplace £15 cheaper than brand new so I thought why not. I have bought games in the past once they are installed who cares if it was new or not.
However once again steam ruined things for me. Steam is an on-line game delivery service and it seems the distributors Activision choose Steam as the security mechanism. Steam requires the internet to work correctly, which causes problem at the lans were we don't have an internet connection. It used to be insurmountable but as internet dongles become more prevalent there are ways around it.
On installing the game I was asked to enter the code I did so, it was rejected as a duplicate. OK I thought well there must be a reset process, so I looked it up. I had to send the invoice and a scan of the code (printed on the manual) with my Steam ID written above. I did all this only to be told by steam they did not support used games suppliers. So in a stroke steam have killed the used game market, at least for steam game, nice.
Fortunately after contacting the Amazon seller I managed to get a refund.
