>all the text, sounds, textures models are present on the client side alone

This isn't entirely true. All the quest text, monster says, NPC interactions and more are sent by the server. Sure, the models and sounds are part of the client, but the server tells your client where to place which mobs, how much health they should have, how they react to you, etc.

>The content that is available on Nostralius is literally not available on any live server any more

Yeah, hosting a game server that is no longer available because the company that used to host them stopped offering that option should probably not be against the law. Even single player games are being created as "multiplayer" nowadays, so it's bound to become an even bigger problem in the future.

You're absolutely right, this is a larger issue (not just with games but with "always-on" and connected devices in general).

It's one thing for a company to shut down an older game's multiplayer-only services when the player base dwindles, but with many single player games now requiring a server connection to even function, what happens to those?

At the very least, companies should have a contingency plan for making a "sunset" patch available to allow those games to keep working - even in reduced capacity - once those servers go away.

Where do you draw the line? Should I legally be allowed to run my own League of Legends client that is current version - 0.0.1 since that's no longer available to players, and offer all skins/runes at a fraction of the cost to my user base?

There is something of a problem here, but the solution (as ever) is not a simple one.
