I agree it is a bit over priced. I got the recent release of Tony Hawks Pro Skater HD on Xbox arcade for 1200 points. Thats a full game, with multiple levels, online play, unlocks etc for less than DG. 1200 would have been the best price for DG in the content vs cost stakes.
Though I cant agree that arrow crafting should have been in the vanilla game. There is no real need for arrow crafting, merchants have more than enough arrows to keep you topped up with plenty. Its a nice addition yes, and very handy but it was not by any means required.
I think the lack of fletching in the base game is an obvious oversight, similar to the lack of dragonbone weapons. Not necessarily
needed, but they should have been included. Before Dawnguard, using console commands was the only possible way to get Nord Hero Arrows, since stores don't sell them and you couldn't make them. Personally, I feel including these things in the DLC vs in patches seems a little cheeky, considering I do feel they should have been in the base game, but I can't hold it against Bethesda that much.
