Rosco120: how did we get from "Good Old Games" to Games that aren't even finished yet?
More or less because the gaming industry has changed significantly since the days of "old games" and whether us individual gamers like the direction things are going with individual issues and practices like this, consumers are the ones who are making it happen by way of their spending habits. When companies try out a new business strategy like "Early Access" for example, and people buy into it over and over again to the point where that business model is confirmed profitable to the companies that do it, then they do more of it. Everything we see happening in gaming nowadays is a direct result of what consumers find acceptable in numbers that are large enough to confirm and justify doing it on the bottom line of a spread sheet.
Companies either adapt to this, or they are pushed into an ever decreasing niche market, or out of the market altogether. See Desura and Shinyloot for details.
To be honest, I don't particularly care for such industry practices myself either, and I do not support these things I dislike via spending money on them. So for example I wont ever buy Early Access games (whether they're being called that or using some other terminology like GOG is using). My wallet vote is very small however and insignificant so it wont change the industry, nor will anyone else's.
All we really can hope for is that some companies out there continue to put out gaming goods that we want to have under terms and conditions, etc. that we are comfortable with, and if they do then we'll have something out there that interests us for the exchange of money. If not, and the entire market goes in a direction we do not like and there are not really any games coming out that we're individually interested in, then I imagine one at a time we'll find something else to do with our time, or we'll play the games in our existing massive backlogs and tell campfire stories about how it was in the olden days while young punks roll their eyes at us.
