This leads to the other games. Civ 2 is still the player's choice. Since then, it's been my favorite game, because it's exactly like Civ-1, except it's got more things and better graphics. The governmental structures and the AI is better. In a scenario, you can have time running by days if you want to.
Good scenarios are extremely difficult to build however.
I've built a few scenarios over the last few years, and each one of them took a really long time and a lot of attention to do. For the European ones, I had to search for old maps of England and France to properly place and equip the cities. For the US Civil war, I needed to figure out Union and Confederate troop strengths and the American infrastructure in 1860. Even with this one I just finished, I needed a lot of historical knowledge. I've been working on a scenario for the last year or so, going in for a few hours a day every so often to add a little bit here and there.
