When I were a lad, well in my early 20's actually, PC gaming was in its infancy and just starting. Back then gaming was a new thing. It was original and different and whole new world was opening up. My two favourite non A/C sim games at the time were the Wing Commander series and the Elite series. Well now David Braben and Chris Roberts are back. Have a look. I for one can't wait and I feel like a kid again waiting for christmas.
