Never thought I'd see the day when a Stardock game required Steam. This is very disappointing.
Some have made the case that Steam has improved a lot over time, and I admit that it has been a few years since I last had anything to do with it, so I would like to ask the following:
1. Would I be required to authenticate for anything beyond updates, the initial client download, and the use of features that would have required internet access regardless of the game's distribution method?
No. edit - to be clear, some publishers may have their own extra authentication, but nothing beyond logging into Steam (online OR offline) is required to play once it's downloaded. This is different than Gamestop/Impulse, in that you do still have to login. However, you do not need to be connected to the internet.
2. Would I ever be forced to update (and therefore authenticate) to continue playing a game I have already installed?
Once you download and initialize, you can set the game to not auto-update. As I mentioned in post #62, publishers will still occasionally force an update. However, if you want to avoid this rare situation then turn Steam to offline mode and it will never even know if there's an update to be had.
3. If I somehow lose access to my Steam account, would I also lose the ability to play games that I have already installed?
You log into the client in order to play the game, so I'm not quite sure how you'd lose access. That said, you can re-download Steam however many times you'd like, and likewise Legendary Heroes. Offline mode is always available for a game once it's been initialized, so there's no "always on" requirement that Steam brings with it. I will say that occasionally (around once a year) I've had an issue with a corrupted file in Steam that prevented me from logging on with my saved password and user ID. All I needed to do was delete the clientregistry.blob file (which holds the saved data) and log in again. If you are instead meaning what would happen if your account is closed by Steam, all licenses are revocable. Like I mentioned above, don't tick off valve while using your Steam credentials. If instead you're worried about Steam going out of business, they would supposedly unlock the games. However, it has been actively speculated that doing so would place its officers in legal peril and therefore it would likely be something that individual publishers would address. IANAL, so I can only offer an uneducated hunch that it's unlikely for any company (in business or not) to suddenly provide millions of completely unlocked games with no DRM whatsoever, especially in neat and tidy digital packages.
