If the guy only owns metroid-style CV games, chances are, he's not a veteran. If he can't get past the first level of RoB, not only is he not a true CV veteran, but he also needs to play more classic games.
If he wants to be known as a veteran, he needs to play more CV games and needs to get good at them. I'm not saying that he needs to beat each one he buys, (it took me years just to beat the first one), but looking at the games he already owns, I'd say he needs about 3 classic CV games (not Metroid-style) AND needs to finish at least some of them before he can call himself a true veteran.
Let me just clarify, for newer members of the CV fangroup, that you don't need to be a CV veteran to be a fan of the series. Nor is it true that a fan is a worse gamer or that a veteran is a better one. It simply means that veterans have more experience in the CastleVania series in general than the fans do.
(Man, I keep trying to edit this to not sound like a jerk, but I keep finding something that seems concieted...)
