nghtmre15: GOG has three things going in its favor that most other digital distribution outlets don't.
1. Nostalgia. Extremely old games that many of us remember playing long ago, and would absolutely love to play again.
2. Extras/fixes. Now all of these nostalgic old games can run on modern PC configurations without those pesky bugs and glitches. On top of all that, you get copies of all the goodies that came with games back when the boxes were huge, the manuals were thick, and reference cards and maps were commonplace.
3. Value. I can show up on GOG one day and walk away with a game for the price of a fast food meal, and it will both last longer and be far more satisfying.
Anything that is done to infringe upon any of these points weakens the site as a whole. I can safely say that there are only a few games I would throw down more than $10 for in the field of possibilities for GOG, and there are all too many sales that could be lost through overpricing.

Snickersnack: Now? Why do you say that?
Is it the countdown?

Lou: You forgot 4. DRM Free ;-)

Tsunami: Thanks for the Raise Dead spell:) It's a nice time to re-visit the price points.
I hope they expand into newer titles with higher points. That way we could get get newer titles without DRM without having to wait for years for them to fall in price. It'd be good for GOG too, as they would get higher margins and not have to depend on high sales every month.

DrIstvaan: Without getting myself too much involved in the core discussion, I'd like to point out that some users actually take some offense when newer games are released. Check out the thread for the arrival of Driver: Parallel Lines and, most notably, King's Bounty to see what I'm talking about.
Note: I don't say we have to stick to very old games, just that it may hurt GOG's popularity in the "purist" circles.

Tsunami: That's a valid point. How about a sister site that uses the same infrastructure behind the scenes but open to newer games as well? Something like "DRM-free Games"? Sure, it'd raise costs, but would significantly raise revenue for GOG.

Starkrun: the fact that they are all DRM FREE would help me justify any new price point, as long as the content and the scope of the game warranted it. Doom3 with expansion 100% DRM free? id drop $20 for that and not think twice

jamyskis: Part of the appeal of GOG.com is the low price point. Go any higher, and you'll have eBay and retail as serious competitors.

Weclock: If they go higher, they will also go lower.
Also, even if Retail and eBay are in the mix, they won't be DRM free.
