Why? DS online component es optional and unnecessary.
It's still a major component to the game (as well as every other game in the series) that adds to the experience (co-op with a friend or random person for an area or boss fight, or invasions with other players). Remove it and now a bunch of stuff (weapons, spells, covenants) are inaccessible unless your grind/cheat or rendered completely worthless. I fail to see how that's a positive.
Not as far as I know. Invasions are very annoying. And there's no way to prevent them, but playing it offline. So I know some people that did so, and finished it offline with no problems whatsoever. There are other stuff attached to online games, like guilds that forced you to help or invade people of different guilds. Basically, some redundant features that need a user base.
Tying a game to that type of online goes against any game preservation purpose.
If the game's multiplayer is still intact and doesn't require GOG Galaxy (a program bundled with it like Terraria or something built in-game, made by the developers or fans, that allows for custom servers or peer-to-peer connections without the use of DRM), would that still go against "game preservation
"? I didn't say (or even imply) that we keep it tied down to the online that it currently has.
Then again this is even assuming that From Software/Bandai Namco are even interested in doing anything else with the PC port of Dark Souls.
From Software/Bandai could release a drm-free version of the game. But in no way can I see them working on a drm-free time-proof version of the offline component for marginal sales. They didn't even do a proper port of the first Dark Souls on PC.
So that's not even in the cards. The question here is whether people would accept a drm-free offline version of it.
