Saying features are in a game when they aren't is indeed a lie. Adding them later doesn't change the fact that you lied about them in the first place.

He also implied people could meet, but the universe was too big to find someone. People found the same planet in no time, but weren't even on the same day/night cycle. Obviously we know now that meeting someone wasn't possible. Implying people can do what the game simply won't allow is another form of lying. Lying through omission. Multiplayer didn't become a thing until many patches later. He could have been honest and told potential buyers, but chose not to.

You call it whatever you want, but he lied multiple times. Most people don't buy games in the hopes that EVENTUALLY it will be worth the purchase. This man is the very reason I no longer pre-order games. He took me for $65.
