Yes, idea two, Discovery should be built around the players RPing, not the devs and their descending hand of God dictating everything that happens. However, with this, I do believe there should be certain limits, I haven't thought on -this- yet.
Want to know why I think this way?
To stop things like Gallia happening, where the devs introduce something so wtfpwn powerful with no real reason other to stretch their epeens, all the while, making the players rage because they had little to no say in it.
