Thanks for the comment on "Omicron Zone"!
You did raise a good point there. From my point of view, in the past video games were a complete escape from the real world and inserting ourselves in abstract, new world on where things didn't work as in the real world. Also, that meant we had to use much more imagination when playing, which made playing those games an experience one can hardly forget. Now, most games aim towards realism, to create a virtual world that is similar to our real one, like living an alternate life inside a videogame, rather than trying to escape from the image we have of our real world.
Indeed, our mentality was different back then.
