In comparison to the Virtual Console, where you can buy such 'classics' as Urban Champion for 5 quid⸮

No. GOG games are amazingly valued. Sure, the pricing is a bit broad, but how much can you finetune a price?

Addendum: Really, if you can't afford 15 dollars, you should really look at yourself and wonder where you've gone horribly wrong, financially speaking.

Regular prices - expensive - me not touching
Promo/discount/sale prices - excellent - me buying with a smile

Speaking as a bit of a cheapskate, no.
The vast majority of games are under $10 and if that is too expensive there are sales every Monday, Wednesday, and weekend.

Well, all those that are considerably cheaper elsewhere are obviously too expensive here. DRM-free might make a game worth more than its DRM infected counterpart, but that only goes so far. Considering that it's been true for years now that I can buy all four Unreal games here for less than the price of one (DRM-free too) then clearly they're overpriced.

I don't think they're too expensive, generally. But I admit, if I'm about to take the plunge on a game, I'll check around to see who has the best price first.

But I don't tend to play whatever the flavor of the moment is; I'm more interested in solid, in-depth, long-lasting games, not art projects. :-) There's a lot of stuff out there I'd probably never even consider, so comparing prices on what are to me completely different things doesn't get very far.

Is it bad that I forgot entirely about that experiment until now?

My first experience with GOG was because i searched for an legal copy of Fallout (without DRM).
That said i bought it and other games. Than i realized their prices and promos.
GOG is not too expensive....nah but they are not flexible enough with their prices.
Selling the games with fixed 5.99, 9.99 or 14.99 just ask us to wait for the next promo.
Its OK to sell new games at normal prices, heck they are new and you want to try them.
But most games are old and it doesn't matter (for me) if i must wait some weeks or month till
they are in a promo.

Nope.

GOG originally sold 6 and 10 dollar games. I think their decision to go higher then that to sell indie games, while refusing to sell indie games that cost less then $6, has skewed things a little, and there are a fair number of indie games here that I wouldn't buy at full price. But I wouldn't call GOG as a whole too expensive, no--I think six bucks for Shadow Man is an absolute steal, to pick a current example.

So to sum up: No. No they are not.

No, they just need more price points as has already been said.

No GOG's definitely not too expensive!

They are a business after all, not a charity, and considering the work they've put in over the past few years I'm certainly not complaining.

All are good points, and it's of course very hard to know the full truth. But as it stands, it does look like cheaper prices = more net profits to developers. I understand the doubts (and I have some myself) but it does not look like there is reason to believe 'undercutting' prices is bad for the industry at all. On the contrary, it looks like cheaper prices mean a healthier indie industry and a longer 'shelf life', i.e. quality games keep on selling for years after release. If cheaper prices have a negative aspect, they have positive ones too. Probably more.

I believe (though of course I can't know) is that gamers are willing to pay more for games they want to play more. I don't think the situation is the same as with the app market, where most buyers see one game as good as the next and therefore look mainly at the price tag.

Also, I believe cheaper prices doesn't automatically mean less money infused into gaming. Cheaper games have brought in customers who would not pay $60 or even $10 for a game. Gamers don't seem to spend less but more. Back when we paid $50 for a game, did anyone have a backlog? Do you know a single gamer nowadays who doesn't have a backlog now?
I'd think cheaper prices would cause more people to afford gaming.

I see no indication of gamers (and I mean gaming hobbyists, not casuals) wanting to go F2P.

Ambitious projects don't necessarily require big budgets. Fancy visuals do. How cheaper prices affect the AAA industry is hard to say (personally I don't really care) but I have a feeling people will be willing to pay more money for the Grand Theft Autos and Call of Duties as before.

Then again, people with no preference will have less reason to use GOG. GOG has the extras and it's DRM free, but I don't think most people would be willing to pay extra for these things. At least not much.

Really cheap prices also attract casual purchases. A lot of times it's not people wanting to buy a specific game and comparing the prices in different stores, but they happen to see a game in a deep discount and buy it on a whim.

Does it ultimately matter if most buyers will never play the games? The player base for Spiderweb, AFAIK has not shrunk, so no negative difference there. The only real difference is that the profits (I hear) have grown considerably. I don't think that's a bad change.
