Nothing about taking a turn requires you give a rats ass about the turn number. When taking a turn you are generating planning and the whole thing creates experience. Experience is far more memorable than trying to hold on to a number in short term memory. I have GREAT long term memory and horrible short term memory - very tough to hold on to something so irrelevant for even a moment thanks to its irrelevancy.
That's true, using more then one sense, visualizing situations, projecting stuff to happen, all this helps in remembering and training. My grandma always told me these stuffs. She wished that I would read aloud when I was studying something hard for school because then I'd read, speak and listen to the subject, which would help me memorize.
Because this is a strategy game and I plan my strategies as deeply as I can, evaluating any possible way I can get an edge, I know what I'm waiting for in various places, what I'm headed for, how long I have before a city will grow or a building will complete or a tech (especially this as I obsess about how long it will be to the next tech) to complete, how many rounds are remaining for a key improvement to finish being built by the workers that are doing the job etc... Nowhere is the turn number a strategic factor in all that.
Couldn't express myself better then this. We play very alike. It is impossible not to see almost immediately that a turn is being repeated. Even if I still didn't stumble upon something that clearly is a repeat, the flow of the turn seems familiar, which triggers me to check if something that I'm sure in which state it was last turn remains in that same state. If it happens to be in the same state then it's a repeat. Even on these yet small games, counting tech turns, building turns, explorers turns makes it easy to double check if something was indeed a repeat. And when the game is already big like in the Massive MP, then there are several aspects that can trigger the perception of being the same turn.
Especially when nothing is automated. I don't know you guys, but not even my mayors are allowed to do their job. Every pop point is assigned where I want them to be, every turn, like each worker does the improvement I want where I desire it to be. No group of workers work together, each individual worker does its task so to not lose the possible work of a worker which happens to be bounded into a group of workers where at least one other don't have move points any more. No city decided its buildings, no Espionage Point is spent elsewhere then on the targets I have, with the weights that I choose. Not a single exploring unit did a single movement that wasn't a command of mine.
My turn is divided into 3 parts: Mobilization and Infrastructure first, then City Management and Advisory Session (techs, civics, espionage, etc.) and finally War Tactics. And I save upon completing each step so if I have to go or a crash happens I don't have to do everything again. It takes at least 20 minutes to do my Massive MP turn, but many times it goes almost up to an hour.
