Very true but for some reason it never adds up like that. If you stuck your stuff on eBay my bet would be that you would get more money separating it all. When people buy a console usually all they want is the console, any games is usually a bonus. I would'nt pay £400 cos I don't particuarly want each and everyone of those games you have. I would be looking at £230 for the console tops and then £20 each for Ridge racer, ghost recon and tiger woods totalling just under £300. The other games, to me, would be worthless.
At the end of the day I'm sure there may be someone who wants ALL of those games and is willing to pay the dollar your looking for
