If you look at the charts, Hitman seems to be quite successful, despite the huge backlash.
How many copies were refunded?
I've made it very clear I don't think this game should be sold here in its current state. That doesn't mean I'll pretend the vast majority of consumers care about such things. They don't. The forum members here are absolutely more zealous about DRM than the average person.
Right. The vast majority buy on Steam. You're posting on the GOG forums. This is a store where the sole selling point is DRM-free. If you didn't care about Hitman being DRM-free you already bought it on Steam years ago.
Something else I'll do is: I want to play a game when it's hot or newer, so I'll just "buy" it where it's at. So, if it's on Steam, it's on Steam - yeah, I'll grab it over there.
If I don't like the DRM elsewhere (on Steam, Epic, Origin, etc) and say it comes to GOG - especially if I didn't spend a good deal on it; or I really like the game a ton - if it comes to GOG and I'm looking for it DRM-FREE, I'll re-buy it over here on GOG.
Sometimes on GOG - there's fixes not in other version; way less patching non-sense and/or DLC chasing to do (think NWN2: Complete); nice mods equipped out-the-box (Vampire: Bloodlines comes w/ Wesp's Basic Patch, which is what I use the most for that game normally); and/or other things worthwhile in the GOG version, which aren't elsewhere.
Obviously, I'll re-buy a game b/c a game is DRM-FREE on GOG - but sometimes it's more. For example, I re-bought Saboteur for the mini-map fix. I bought Riddick: Dark Athena to get away from its crap DRM. I re-bought Jade Empire: Special on GOG to get away from its disc-DRM. I bought Vampire: Bloodlines b/c it comes w/ Wesp's Basic Patch. I bought NWN2: Complete to have the game entirely patched-up and get away from its insane patching process; and to collect Mysteries of Westgate (yep, I was missing that DLC).
