The problem is that you - and apparently LGP - are thinking this like developers. You're not salesmen. It's not your job, and you could have insane programming skills, but still you just can't sell the goods, because it's not the job you're good at.
You're saying the price can't come down, and for you it ends the problem. If your job is to sell goods, that's never going to stop you, and I'll try to detail why :
Imagine the game has to sell for 40£ to make a profit (yeah, LGP doesn't advertise their goods in any other currency, and that just show how they want to make sure they sell the less amount as possible). Now you still want to drive the sales, not just sit idle on your chair hoping nobody notices you've got something to sell. So what do you do?
First, you could make a special 1 month pre-release deal. For 5£ in advance, you'll get the game 5£ cheaper. Oh, but - thinking like a developer, it won't work because you need to sell the game for 40£ to make a profit. n00b. You price the game 45£ or even 50, and you still sell the game for the amount you wanted to sell it. More important, 5£ is below any impulse level, so you'll get people signing up that would never have bought the game for a boring 40£. You get more customers, you realise you could sell the game for 30£ and still break even, but for the time you could save up the 10£ free profit to pay for the rights of a next game, a bigger one.
Now, when a game has been on sale for 2 years and you notice only 5 people a year buy the title, are you going to stick there with your head in the sand keeping your game at the price you need to break even? n00b. Slash the price by at least 50%, sell it for 20£ or less, or create a bundle with two games at 30£ each. Then please, do ADVERTISE. Pus banners on your site. Make it a special offer for a limited time only. Send notice of this to all Linux web sites and publications - bargain sale at LGP, limited offer, get it before it runs out! Most, if not all linux magazines, and all Linux websites are run from fans, and they'd like Linux gaming to be successful as much as you do. If you're even half as skilled in human relationship as Torvalds is , you'd get them to inform their readers for free - it's their job, and they'll be helping their readers save money.
Now, to go back about LGP's (lack of) advertising - the man couldn't sell whiskey to an alcoholic. I had to come back to Phoronics looking for reviews of the HD 4850 to remember that X3 was still being ported to Linux.
Isn't it symptomatic of a problem? The game is supposed to be released in a few month, yet nobody's doing previews, nobody's sending daily screenshots to Linux sites, no one sent the beta to each Linux journalist and their mom (same for at lest one or two people in big distributions like Fedora, Ubuntu, Mandriva...), no one's running monthly interviews of the developers... What? Are they afraid people might think of buying the game? We're not talking about having to fork money to buy a few pages of advertising, we're talking about things that wouldn't cost LGP a dime.
When you go to LGP's site, it's like the man is running a charity. Yeah, even if you don't plan to play the game, give us some money to support gaming in Linux. Sorry, but if I've got 40£ to throw somewhere, I give them to real charities, people needing water, food, medication, teaching... (and before you ask, yes that's what I do), NOT to save Linux gaming, because yes, there's a sense of decency somehow, and a life is a tad more important than an agenda.
So, except for a few person, people will only give money for games (or software, or anything else) when they know they're getting a value out of it. Yet what value do you get from someone that doesn't even behave like what he's selling is of any interest for the Linux community?
I'm not saying putting DRM in the games are or aren't going to help him sell a few more games. It's his call, and that's his problem. However, I (and I'm not the only one) have got some gripes with the way the man is running his business.
Look at X3: Reunion - Special Edition.
Yeah... Can't even be bothered to tell me WHO wrote the freaking book, or what's the story about, or if it's even remotely related to the game? For what we now, it could be the perfect book to help you start a career in gardening, or another illustrated story with Winnie the Pooh and his friends. The T-shirt? Could be any cheap quality fluo pink ultrathin polyester with a 5mm≤ logo in front, where you could only barely distinguish enough to be sure you're telling everybody you're into X meetings... and what, nothing about a manual or an irreplaceable map of the X3 universe?X3 Special Edition comes in an old-style big game box, containing the regular X3 game, along with an X3 T-shirt, and a copy of the book, 'Farnhams Legend'. This is a limited edition run of 500 copies. Each copy is numbered and signed by the CEO of LGP.
The man may have done a lot for Linux gaming, but wouldn't you expect him to try selling the goods he's sitting on?
Now, to the man's defense, he's running his soceity like a developer would like his goods be sold. Don't ask people to sell a kidney to buy the goods, price it at an amount that pays for the development (+ the royalties) and no more, so you can keep doing the job you like.
Fair and nice, but we don't live in such a world. And LGP is selling somebody's IP, an IP that has needed the efforts of dozens of developers and artists for a few years. Sorry, but a village's general store mentality isn't giving them any respect. Moreover, selling selling games for a premium after they've been on sale for years isn't really giving the consumers any respect either, however "fair and nice" one wants to be. Doing a better job selling the goods, making it desirable enough, selling it for more than what you'd say is fair at the beginning but giving people real value for this money (the value isn't in the box only, it's in the sale, the shop, the site, the buzz, the community, the interaction with the company and the devs, the informations you get bit by bit and the dreams you're allowed to have), then having covered your expenses enough to offer the games at bargain price for those that fancy retro gaming (after 2 years of LGP sales, and considering the games were released on Windows 2 years at least before LGP delivered the Linux port, yes, you're selling games to retro-gaming fans, not any gamers) - that's proving developers & clients alike due respect. If you're a salesman, then doing your job well is as important as for any other job.
