That's interesting because I'm having to deal with this debate not here but on Kickstarter. A lot of the Kickstarter projects start having this debate about 6 months to a year into their development. I'll explain why in a minute. I only use Steam when I'm forced too. It does have its plus and minus but I will always choose and pay more for DRM-free options. If they put Bioshock Infinite here, I'll pay full price. I'm really thankful for GOG for DRM-free and no-CD check.

I support new PC games being develop on Kickstarter but I'm starting to see a disturbing trend. I'll use the Kickstarter PC game I'm supporting as an example: Dead State: The Zombie Survival RPG

Dead State is IMO a very promising survival zombie horror game that contains RPG. I have been watching it even before it was put on Kickstarter. When you look at the main page that shows the Pledges: You see DRM-free, DRM-free, DRM-free. I'm thinking the developer choose this because they were not greenlit for Steam and there was no guarantee that there would be. So backers pledged to this game and I did too because it said you will get a DRM-free copy of this game. Because Steam is the majority and give tools for developers to do "early access" which reaches a wide range of potential customers, many developers want to use it. So a post came out 10 months later that said they were greenlit but they were careful to say DRM-free and Steam are equally supported:

We will still be offering DRM-free versions, but for those who want to activate on Steam, that option will now be available.

Although we were told the beta was only going to be released on STEAM. That happens a lot.

But the post that got the DRM-free vs Steam debate started again was on Feb 8, 2014.

It was frustrating to be told that the beta would only be on Steam. But in this post, the developer made the DRM-free backers feel that the Steam version was more important, and went on to given reasons why Steam was a better choice. Of course they said they would give you a DRM-free version but they didn't make the backers who support DRM-free feel better because of how they presented themselves in the post. They also said they hadn't look into other service so don't ask for now. But it felt like a slap in the face to DRM-free backers. The developers are so commented to Steam at this time that although they said they would eventual release content for the DRM-free version, Steam would get updates first. But there is no guarantees.

I posted this:

I'm very concern with the trend I'm seeing in game companies using Kickstarter when boasting DRM-free to get support funding and then nudging backers to use STEAM after they have been greenlighted.

I also said:

I do get why the developers wants to use STEAM and listed a lot of good business reasons to use STEAM. I just wish more game developers would create post like this one on day 1. (ex. If we get greenlit we are going to primarily use STEAM) I would appreciate that more.

Of course the Steam supporters, who are the majority, were saying how much better Steam is and how DRM-free backers are whinny and complainers. Of course, it's easy to do that if you would like and prefer the game on Steam. The developer boasted that 99% of the backers even preferred Steam which I don't totally believe. Some Steam users really believe that it's not really DRM. If you go to wiki it says its DRM in the first sentence.

One the Pro-Steam comments posted was a link to how more than 50% of indie-games sales come from Steam, but the article for Defender's Quest actually praised GOG and said GOG was going to continue to grow and be an excellent alternate to Steam in the future. The data showed that a game developer is neglecting about 20 to 40% of their business if only going with Steam.

So I had some thoughts for GOG in helping becoming more connected with Kickstarter projects. The Carmegeddon Returns and Wasteland 2 Kickstarters seem to be connected from the start with GOG. I think if GOG had a team that reached out to more Kickstarter projects as they are first starting to get them interested in using GOG, maybe more developers will embrace GOG from the start. I get very worried when developers switch more emphasis to Steam also because of DLC. Meaning we will get a DRM-free game as promised but ignored after that for future content.

But this doesn't address the other issue of early access. GOG business model is restoring and updating old games to work on modern operating systems. I value this so much. But if GOG starts to get more into promoting more current games, maybe GOG needs to start looking into an early access of their own to compete with Steam - if not for all games, maybe just Kickstarters projects. The reason being is the backers have already paid for the game so there is no worry of piracy.

These debates will continue because Steam's biggest strength is convenience. That's what I read from Steam users. Steam creates a library for you and updates the games bought. You don't have to think too much. You buy the game, install it, and then play it. I agree to a point BUT Steam still controls the account and library of games and can take it away with an updated "terms of service" contract issue and other horror stories I read on the web. I remember that one time I went to play a game on Steam and the client got corrupted. I spent 6 hours fixing it and lost my day playing a game.

But the biggest convenience for me is being able to play my game independent of any service and even the internet or CD check. That I can preserve the PC games I love most and they are with me even if a game company or game service shuts down; that I can play them when I want to not when someone else decide when I can play them.
