If you are starting a new character anyway, a list of the level requirements for skills would at least be of minor interest (ie handy but not essential, IMO). That info would be much easier to get from the PC version with the help of a trainer, though, especially with some skills having extra levels available if you boost them enough in a new FoV character. To get this info in the Xbox version you would have to keep a lot of skill points in reserve in order to check skills each time you went up to a level to meet the lowest skill requirement (that was previously unavailable).
