Huh… I don’t exactly know what to vote. I understand the problem, but none of your options sound like the correct solution to me.
When people come to the Blender Game Engine board and ask questions about the Blender Game Engine, they usually want answers to their questions within the framework of the BGE (which seems to make sense).
However, there is a time and a place for recommending alternatives. When people want a nice, working web plugin for Blender content, and they are not satisfied with the outdated 2.25 plugin or the alpha testing version, IE only 2.42 plugin, it is nice to be able to recommend the BS Exporter from BitManagement.
I think the problem has been (as far as I am able to perceive it) that you have been a bit over-zealous in offering those alternatives, even when the author of the question has not suggested a desire for an alternative.
When someone comes here, it is because they have put some thought into it and decided to learn to use Blender’s Game Engine as opposed to the other options. They may not know about Crystal Space (or the very polished and easy to use interface with Blender that it offers), and I agree with you that they deserve the opportunity to know about it and make an educated decision. However, there are appropriate times and ways to offer that information. To most people here, your constant references to Crystal Space probably seem like shameless plugging and product evangelism.
Please don’t misunderstand me, though. I’m not saying people are right to feel that way, or that it’s wrong of you to share your thoughts and experiences with CS. It’s wonderful for us to have active users of Crystal Space and Blender on this forum, because you are the ones who will be able to answer questions when people who use the CS + Blender combo are having trouble figuring it out or getting a certain feature to work.
Perhaps the best solution is to only offer alternatives when the author of the question seems to desire them, and for us to have some sort of list that shows new users what the various game publishing options are with Blender (at-a-glance) so that they can make an informed decision.
