Did you know? In Mortal Kombat Deception, there is an optional side-mode called Konquest, which is a full-length open world RPG with a day and night cycle, a week/month/year cycle, a weather system, six huge separate worlds, and having your character age in real time with the world.
Though rough around the corners and often misunderstood by folk who just wanted to rip people's heads off in a fighting game, it is actually surprisingly quite complex in how much effort they put into it and, more importantly, extremely comfy with a very relaxing soundscape. You can just stand there in a dzen-like tranquility and watch as the world moves by you.

And all that is just a side-mode in a fighting game, like the 5th option in the main menu. This could have easily been sold as its own thing, yet they included it as a bonus in another game. Can you imagine something like that nowadays?
