The Elder scrolls
You put it perfectly here
I would have loved to have played it as a kid with childlike wonder
That feeling you get when you play a game you like when you are a kid is something you don't get again as an adult, I remember the first times I played Minecraft, I remember that sense of adventure and discoverery that sadly I haven't been able to experience again.
I can only imagine what would have felt playing Morrowind, Oblivion and even Skyrim with the mind of a child.
I know these games are not that old... but hey! I was a child when they came out.
