LiquidOxygen80: DRM will not make people more likely to buy your games.
Hard to say, it is a complex thing to sum up in one sentence like that, especially as there are different kinds of DRM. Some thoughts:
- If certain DRM system gets bad press and clearly inconveniences the users, then it will most probably be detrimental to the sales. Many people will avoid the game due to that. Maybe this has affected Denuvo a bit too, the reports of if causing crashes or poorer performance.
- On the other hand, I do believe that some kind obstacles to freely copying around the games may make some people, who had otherwise just pirated the game, buy it instead. Take for example that Serbian guy here who says he is entitled to pirated and free games because Serbia is so poor (yet he can afford a PC and.a broadband internet connection?). I'm pretty sure if he was unable to pirate any games, he would buy some (or get them otherwise in a legit way, I guess that's why he is begging for free games).
Note that this doesn't have to be only DRM. It could be also that the IP rights holders try to actively hunt down people who share or download pirated games as torrents (making it less lucrative for many people to share or pirate their games online), or merely some kind of watermarking system that doesn't prevent you from making copies of the game, but is still an incentive not to share it around.
I personally would be fine with a DRM system that would stop me from sharing the game to others, but wouldn't even theoretically prevent me from playing my legit copy years (or decades) from now. I just can't figure out what kind of DRM system that would be. No, the answer is not Steam CEG as it is still dependent on Valve, and even may restrict my access to the game when they are around (e.g. like I was suddenly unable to play my games on Windows 2000, just because Valve decided so).
CD copy protections were close to that, but their problem ultimately was that they tied the game to that media. Ie. when the media or the device used to read that media dies or becomes obsolete, I can't play the game anymore.
Even better would be the watermarking system. I wouldn't care if all my GOG purchases had an (uncrackable) watermark which would tell at least GOG, or maybe even the game publisher, that I am the person who bought that copy of the game originally. I'd prefer though that watermark would be incomprehensible to others, ie. there shouldn't be directly personal information in the watermark, only some kind of identifier which the store and/or the publisher could possibly map to me.
Failing those two, I prefer DRM-free. :) I vote with my wallet.
