Sorry bud, Naughty Dog is like that now, and thats absloutely no point of talking about this on the fourm. Most of these people are just drones anyway.
Maybe you souldn't be on these forums if you feel this way then....
Naa I like to voice my opinion. Just calling it as I see it though.
By calling other people "drones"? Okay then......
First things first.
You accept your own post as the solution... yeah okay.
Second, I don't see the problem. Technically, you paid €70 for 4 difficulties.
Nobody in the industry is so bad? Are you serious? You should look at the Tales games on the PS3, or the recent Final Fantasy games. You end up paying €3,99 for a single extra costume, that usually doesn't do anything, or is weaker than what you already have. In light of that, I would say Grounded is a big Bargain Level 3 (Uncharted reference).
