I have an idea that will benefit both PSN Users and Sony: Implement a trade program of PSN DLC (full games and extra content) between PSN users. This forum trade community could be easily accessible in the PSN store, and categorize games and extra content by game genre and/or price and/or date posted/requested.
Each item could potentially be traded from one PSN account to another PSN account for a discount, or point system to accumulate for future purchases. After one PSN account sells/trades a DLC game/content it will be deactivated indefinitely in their account and exported into the new PSN User's account. Sony could profit by charging a small (and I mean small (i.e. $0.25/$0.50/$0.75, etc.)) fee. This, in hand, will kick any used videogame shop to the curb who constantly take advantage of profiting from used video games.
Does this sound like a reasonable idea to keep PSN users active and continue to make $$$ for Sony and their developers, and save a little for the Users?
Long. Live. Play?
