When traveling on the German high speed ICE trains, you have access to the ICEportal website with a.o. information on your journey and newspapers. The portal also gives you some stuff to waste time on, which includes games. What I love about it, its a collection of simple classics, such as a bubble shooter, a 2048 style puzzle, an arcade motorbike game, and all without the typical freemium advertising or grinding.
Does anyone know about similar offerings? I really don't mind paying, I do mind the advertising or grinding which seems to have become standard. Or even better, if anyone knows how to have the ICEportal games without being on the wifi of the train? What are your thoughts?

If there's a better or more commonly used term for this let me know, but my idea of an "expired classic" is a game that was acclaimed and beloved at the time of its release but that would be nearly unplayable or unacceptable by modern standards. Not just less impressive or weaker, mind you, but outright bad. Think "aged poorly" but like, REALLY poorly.

The quintessential example is Goldeneye 007. While absolutely landmark for its time, gamers that pick it up now would likely be baffled by its controls and appalled by its significant, unforgivable framerate issues. Even some people that used to love playing it have a hard time enjoying it now (myself included). It is a game that has "expired" over time.

The expiration doesn't have to be due to technical issues either. It could be due to cultural issues, design issues, or any other factor that makes the same significantly less palatable today, even to those that want to play it!

What are some other examples, and why have they expired?

A classic can be a franchise or just a standalone game. Some examples of current classics can be old arcade/Nintendo games such as The Legend Of Zelda, Mario, and Pac-Man, or slightly newer ones like Final Fantasy, Tomb Raider, or The Sims.
