It's a simple value proposition, either you believe it's worth purchasing, or you don't. The fact that you bought a previous version lowers this versions perceived value, but it's not on Sony to compensate for that, it's on you as the consumer to account for that in your purchase decision.Wrong.
No matter how you think of it, I AM supporting them by purchasing their product. Your talk about 'charity release' is not relevant here.
You even used the word 'compensation', as if the release has somehow wronged you. If you'd felt TLoU was not worth buying, and felt burnt by the release because of technical issues not present in this version, you might have had a point, but as it stands, you're not due any restitution. If you believe the game's value is lower than the RRP, purchase it when its price reduces to the value you think is fair having already played it on PS3.
