A big +1 for native GNU/Linux support; if they port the Telltale engine, I'm given to understand, most of the Telltale games should run on Linux at once. That isn't to say it's easy, though.
I think the biggest problem is that they use DirectX instead of directly some OpenGL-based framework. The news from today, however, speak of a Linux port of DirectX 11 to
run above Gallium3D.
I guess that porting isn't so bad as it sounds. Economically, once you did it once, it should be possible to maintain it without going mad; the real problem is a) testing, b) packaging, c) making sure your libraries don't disappear overnight, due to some new backwards-incompatible release (much less likely it happens on Windows or Mac OS X) - you probably want to static-link to them.
However, even considering the poor state of hardware acceleration support for Linux, it would be difficult for Telltale to say "it's not us, it's your crappy drivers" if the port wasn't up on par with the Windows one. That's bad.
I think that on the long term, the most economically interesting way to make some money out of a Linux port, would be to opensource the engine. I mean:
- Do not distribute the Telltale tool.
- Put the Telltale engine under the GPL, so that business rivals could not exploit it without releasing source code for all the improvements that could be ported back to the original engine.
- Make a marketing campaign about this. Mostly, the GNU/Linux community would tam-tam this out by itself, since it would mean a lot for us. We're always looking for "good" companies releasing source code under the GPL. Thus, free publicity for Telltale.
- The community would be responsible for keeping the port compatible; to package it, to make it compile on a pletora of distribution, to improve it to run better on existing hardware.
- Free bugfixes.
After this, why would you still buy the game for Telltale? But why, the artwork. The plot. The puzzles. That would still remain of propriety of Telltale, and could not be reproduced without permission.
Many GNU/Linux users would immediately be interested to buy a game from a "good" company; most of us passed nights compiling ScummVM when it was still a beta project, just to run The Secret of Monkey Island again, while on Windows XP it didn't start properly (the Italian version, at least, didn't). Don't underestimate the passion that links GNU/Linux users to adventure games! There are many of us interested.
Really, a half-working port to be opensourced seems the best thing in my opinion, all things considered. After all, here in hell we all run Linux, and that's a huge userbase (there are more people here than in heaven!). ;-)
