I agree with everything you wrote here in principle, TPQ, but the details not so much...
Marathon is just more fun. Agree about late era fun too. But 1500 turns, whoa! Usually finish the tech tree around 700 with RA's, 850 with house-rule "no RA's after Industrial".
And 300-500 turns a day? I can see that if I ever play an MP game with you guys I'll have to get a partner that's laid back, that's just blazingly fast.
Yeah, I just play into the small hours. I don't really need much more than 6 hours sleep. I've never timed it, but I don't suppose I spend more than a minute on average per turn. I've been playing Civ since the original, so I'm fairly used to how the game works and Civ5 is one of the easier iterations, if not The easiest. I also don't watch TV, which frees up some time.
I hardly ever sign RAs. I just find I don't really need them. I might sign 5-10 per game maybe, if an AI asks for them and I've got the spare cash. But I don't actively seek them unless I find myself with 10s of thousands in gold and nothing particular to do with it, but if I'm at that stage a win is pretty much guaranteed anyway.
Like you said, marathon is about holding back and playing for the later eras. Developing a plan over time and watching your cities and empire take shape and develop over the millennia. I've always enjoyed the developmental process in Civ. I guess I a bit of builder at heart.
I find taking my time much more satisfying than rush, rush, rush, oh I've won with 900 tuns to spare! Woohoo! But of course different people enjoy the game differently. I like the experience to last, others like to play more competitively and look for the quickest win. It's all good.
It's true though, if somebody really wants to, you can hammer the AI into the ground pretty quickly at marathon speed, at emperor anyway. I just don't find doing that particularly enjoyable. I like Civ! I want each game to last!!
