AstralWanderer: Isn't that the situation currently? Playing AoW3 multiplayer involves direction connection to other players' systems with Triumph's server providing a matchmaking service.
Historical note: In the early days of online gaming, LAN connectivity differed from general Internet access as it used a different network protocol (Novell's IPX rather than TCP/IP) and offered significantly more bandwidth (10/100Mb/s Ethernet compared to the then-typical 28/56Kb/s dialup modem). With IPX long gone and broadband connections now rivaling Ethernet in speed, there's little technical difference between the two currently.
Doesn't matter, it's not a direct connection therefor it's not technically LAN. LAN is a local connection, and connecting to there servers is not local.
AstralWanderer: Again, look at previous versions of AoW. Their multiplayer options
did not rely on an outside service (the original AoW did include an option for Sega's now-defunct
Heat.net matchmaking service but didn't rely on it). The only thing able to prevent AoW/AoW2 multiplayer (aside from lack of gamers) would be a change in network protocols (total adoption of IPv6 say) and even then, an IPv4 tunnel or VPN should provide a workaround.
So while singleplayer can be described fairly as DRM-free, multiplayer currently isn't. That makes the fairest description of AoW3 as "partial DRM" or "multiplayer DRM" and the problem is that it then represents a dilution in GOG's DRM-free core value (and just after having the "fair price" one dispensed with).
GOG will find it harder to argue against DRM generally with publishers ("If you now allow compulsory login for multiplayer, why not allow it for our singleplayer game?") which will result in publishers pushing DRM through the back door (e.g. having patches which add DRM like Stardock has done, or requiring DRM initially while "pledging" to remove it in a later update).
It doesn't matter how the past games were done. We are talking about AOW3 and if it has DRM. DRM in general is an effort to restrict or control the consumer/product in regards to digital media. In that respect multiplayer in itself is DRM because it's controlled and restricted by an internet connection, which you are not guaranteed to have access to 24-7.
As a consumer you are never entitled to multiplayer, is has always been a
service as stated by literally every TOS I have ever read... and since AOW3 is technically
not providing you with LAN, it's not now DRM because there asking consumers to make an account or use keys to connect to multiplayer servers that are paid for by the company.
You can be mad that AOW3 doesn't provide LAN or other features... but that doesn't mean that the game itself now contains DRM because they ask you to make an
online account while playing online. Call it stupid, call it a bad game design... whatever... it's not however DRM just because they offer you a service which includes you using there servers but don't offer you away to play locally or with no account. That is a pure
design choice.
Are there other options that they could have chosen to make getting online better and more future proof ? Sure... but it's there game... and
you are not entitled to multiplayer.
Furthermore a large part of GOG games require CD-Keys to be used to play online... so
why are we complaining now? That in itself should be enough to claim GOG games not DRM free. But a majority understand that that isn't the case.
Multiplayer should always be looked at as a bonus... an extra... the real prize is the single player. Why because your only entitled to a indefinite licence for the single player. This is what makes games significant reliance on multiplayer scary.
This is blowing up this situation more than what it actually is... there is lot of gloom and doom in your post and very little fact. Not I or anyone can predict where GOG will stand in 6 months or a year from now.
