Hi, yes you must follow the rules, I myself only list a item if I am 100% sure it's ok, couple of weeks back I wanted to list some items and wasn't sure so I asked eBay and I was surprised by getting a letter to the effect that it's not there job to look up what's aloud and what's not, They just gave me a link, and since english is not my mother tong, it is very hard for me to research that since the list is so long and almost impossible for me to find out if I was able to list those items.
So at the end I didn't list them, so if I am not sure I wont list it, that's all.
if anyone has a better idea on finding out if a item is allowed to be listed or another email address at eBay Please let me know. I spent a lot of Money on these items and now there just in storage or I will sell them to the flea market sellers.
Also super_jossee why don't you just sell the game? you cant just sell the key? it's like buying a copy of windows and then just selling the key, is that what your listing was like? from what i read it looks like that.
anyway good Luck:)
