Someone made a renown chart for GWX 1.03. IIRC the Hood was the most valuable ship on the list with 1500 points. I remember someone complaining that the Bismarck was only worth 1400.
But i don't know if these values have changed with GWX 2.0. I'm sure there is some file in the SH3 folder which contains all the renown points, but i'm no expert on this.
