Think about it. Skyrim was estimated by Todd Howard to be 300 hours, and cost 60 bucks. That is five hours per buck. He then estimated Dawnguard to be 20 hours, but it cost 20 bucks. So, to be fair to the regular game, Dawnguard should reduce its cost down to 4 bucks.
Hi there MetalGod! How are you?
Good point. I myself have brought up this issue before. Some have said the whole gameplay hours / price ratio is meaningless, but I disagree. Since most major development costs - Creation engine, Radiant Story, etc. - have already been covered, I'd say this ratio is even more meaningful now. But realize it’s just one amongst many other factors to pounder upon. With all the info currently available to non-beta testers, I think the price is too steep. My main objection, though, is the theme. I am not interested in vampires.
