You definitely should have put a better title on that puppy. Something like
'Huge Xbox Lot~System+XX Games+2 S controllers+2 Dance Pads' Maybe put Halo 2 in the title instead of the dance pads thing. (As Halo is probably the most popular search term with Xbox, plus people will see your auction if they search for 'halo xbox system'
)
And I'd probably try to get one picture that showed everything (maybe have all the games stacked behind the console?) to use as the 'main shot' - let people see the huge stack from the search page since you have the gallery upgrade.
Or at least instead of saying 'many others' in the subtitle give the actual number (or something like 40+ others)
If you only had like 7-10 games total it might be okay to just say 'many others' but you have a massive list of games there.
Putting 'Black' in the title really does nothing for you as that is the norm. I did a search for your title and there are like 50 Xboxes listed with pretty much the same title. I guess that is the standard text eBay gives you when you use the Xbox console's standard pre-fill? Given that maybe keep 'black' in there, but definitely add to it. Personally, I'd just go with my own thing.
And guessed's suggestions are all great ones. Obviously I think his #7 is the biggie, but #3 is a pretty major mistake as well.
Did you mean to have shipping to US only, or did you really want to do North and South America? (Just seems kind of odd to not include Europe if you are going to do S. America...)
Honestly if I were you I'd seriously consider cancelling the auction and relisting it with a better title and description. I think the way you have this listed could really kill your final value. You can add to your description to clarify that you do in fact have complete games for the list labeled 'game cases' but there is no way to fix the title at this point, I believe. Of course, if your reserve is high enough, you can just let it run and see if it gets up to what you want... If not relist with better info.
