My first time playing Civ, was years ago with Civ 2.
I had no idea what the shields/trade arrows/gold medallions were, so I simply ignored them, and figured the computer based how long it takes to build things, by how big my city was. I had no idea what a tile improvement was, until halfway through the game. I built a single settler, and improved one tile at a time. I tried building more, but to my dismay, they kept disbanding (I had no idea what unit support was). Eventually, I discovered flight. I was so happy, and started building planes immediately. I built a fighter, and tried to fly it my other city (about 5 million miles away, taken over from a rival civ), and it crashed over the ocean. I figured I didn't take a direct enough path, and I try again.... crash. This time, I thought I'd be tricky... I flew the plane to the edge of the water, thinking it would simply land if I kept it over the land and not the water (made sense to me at the time)... I ended my turn. *click away some boring warning messege* ...Crash... I am shocked, I lost 3 planes, of which took me forever to build (remember I hadn't really improved tiles), so I get so desperate that I cheat and nuke the world. The End
