I am very honest and upfront with the community. I will not and do not make console maps. It's not that I can't. In fact, you are right, it would be easy, and I would "make more money". However, in my opinion the map would have to be simplified, and all realism stripped. The rules to make mods console friendly in my opinion strip them of all realism. That and the fact that I am not in this merely for "more money" keep me from doing console maps. Every one of my maps has and always will be released to the public for free. I have never not released a map for free. It only requires patience.
Now to talk about this "culture" you reference. The culture is that everyone wants things for FREE and NOW! Very few people are willing to wait for something that's finished. They want it rushed and complain that its taking too long. But then complain when things are not perfect. This system allows those that want to help make the map better a way to get access sooner. They truly are helping find errors, mistakes and problems. They do this all within a period of weeks, something that would take me by myself 6 months to a year to complete. So, in my opinion everyone wins.
