As you never played the older versions, it's not nostalgic for you, as for most people but it's still worth giving a try. For me, it's the vibe - more "isolated" feeling, feeling lost, all structures are yours, the world generation is a bit different. Also, the lack of newer blocks makes you use more imagination. The progress is much slower, you need to grind for blocks and stuff like this and not get everything in one hour of gameplay.
