I end up selling my games. I don't see much point in hanging on to them once I've completed them. Plus I can then use that money to buy more games.
The only way to fix the problem is to completely use a downloadable system like steam. Presumably the digital copies will be cheaper. I have no trouble buying games off steam as they cost half the price of their retail counterparts, and the steam weekend deals are insanely good. Hopefully by next gen they will have an option download service that is cheaper than buying games at the shops.
