I lost many, many hours to Civ 1 as a boy. It was a rarity in the battle with my parents over seat time as they saw it as educational. Ha!
I've tried to get even remotely as engaged with the new versions but i just can't seem to bridge the gap. In the quest to make them more detailed an deeper/broader they've lost the fun for me. I'd love to see the original game-play, 100% intact and true to the original but in the modern engine for the visual treat. Dare to dream.
