I dont understand people who buy games with always-on-DRM honestly. Why would anyone ever buy a game with that kind of DRM?
First off, you lose the game you bought along with any DLC or microtransactions you spent money on the second they close down the servers. The latest example is Bullet Run where the company decided to shut off the servers very early after the games launch. Granted, it is a F2P game but that doesnt change the fact that you spent money on it and that it intrinsically has got online DRM.
I have many old games I still enjoy playing - X-COM:UFO Enemy Unknown or Master of Magic for instance. If they had had Always-on-DRM, I would not still be able to play them which would really suck for me.
Secondly, if something goes wrong anywhere in the process, you are screwed. Without always-on-DRM you can at least try and fix things from your side but with the always-on-DRM you set yourself at the mercy of a company which most likely gets tons of complaints like yours and may or may not give a rats ass about your case. I am still waiting on an answer for a support ticket regarding Deus Ex 2 which I placed a year ago for instance.
An example of this going wrong is the latest SimCity ban case. Granted, it is a beta and granted it got fixed - but without always-on-DRM, that would never had happened in the first place.
Thirdly: Server capacity. Why would you ever buy a game you cant be sure you can play? If the servers are full, again as in the SimCity case above or as with Diablo3, you cant play the game simply because the company ran out of servers which were completely unnessecary for all the people who just wanted the singleplayer experience.
To me, if I buy a product I want to have my damn product and be able to play it for as long as I want - regardless of the producers desire to keep an arbitrary server, which isnt even nessecary for the game itself, online. I have games from the 90´s I still play at regular intervals because I like them - games like UFO: Enemy Unknown or Master of Magic - and if they had had always-on-DRM, I strongly doubt I would have been able to still play those titles.
Disclaimer: And yes, naturally there are some games which rely on always-on-drm for the player experience and I understand that, with the online aspect in the game, naturally servers will be nessecary and its not likely that those will be up for ever - but with games or modes in games which have no online aspect, why would it ever be justifiable?
TL;DR Always-online-DRM may cause you to lose your game when the company decides to stop funding their servers, they massively inconvinience you (potentially constantly), you are being put at the mercy of the company with the only course of action available being to hope they will bother helping you some time within the next week or so.
I just dont get it - why would anyone ever want to buy a game with Always-on-DRM?
