Tallima: Mr Bradley (we don't use noble classes in the US :-P),
I think you'd be surprised by how many people are very willing to pay for a huge expansion to a game. This game was $60 with a hefty 20% discount for loyal customers making it almost as cheap as Kerbal Space Program and Demonicon on release. I think many people would argue that W3 is vastly superior to those games -- and it certainly took a lot more money to make them.
Strategy guides are certainly not the expectation, but they do come with some games on GOG. But for every newer game that I have (developed in the past 4 or 5 years), I don't have one that comes with a strategy guide.
Also, pre-orders are not some evil marketing scheme built to injure people. It's usually a way to market and get some additional funds to finish the game. If you don't want to pre-order, that's okay. You don't have to. They're not trying to be mean to you by offering pre-orders, they're just trying to make a bit of money and create a bit of stir.
And in CDPR's case, offering a free NWN game out of their pocket, giving early access to some printed content and throwing a 20% discount into a pre-order is quite generous. Most of the time, all you get is buyer's remorse and a shoddy cloth map. So I thought the deal was outstanding.
And the same thing goes with the expansion. They are offering it for pre-purchase. You can get it now or wait a year and get it for cheaper or another year and probably get the platinum version. Those are all your call. It's not bad marketing, it's just the market.
I hope that helps you see what most of us see. If not, close your eyes, spin around real fast, then read this post again.
Also 16 free DLC's.
