I'm going to go out on a limb and say also that you should expect message boards and forums to be different in the video game industry than they are in the healthcare/medical industry. I don't treat these forums the same way I would if we were talking about health and medicine and if you are holding me to the standard of serious moderator of serious issues rather than gamer moderator talking about zombies etc. then maybe you are the one not relaxing quite enough.
I do agree 100% with you that when the game is released and published to customers as the finished product it better not have this level of buggy garbage or it will be completely ridiculous. But as often as people bring up the erroneous idea that the experimental version can't have known and largely untested issues I'm willing to poke the necessary holes in that viewpoint.
To tie it in to your industry: Experimental drugs can be opted by patients who are hopeful for a cure but there are probably known side effects and issues that can be pretty bad. Yet, the patient can still choose to participate in drug trials for medication not yet released or approved for public consumption. Same is true of the experimental version. You must choose to opt in because it is not ready for public consumption.
Cool.
