if one could match players of innate equal ability -with one having lost four games and one that won four reloading and ran that test with different age groups and sexes and computers about seventy six times then one would come to the conclusion that the reloader would have retained more relevant information in regard to how to "manipulate game conditions" and would beat the non reloader hands down.
Beyond that being a "fact" that was pulled out of a rather dark place, I'm really not seeing it at all.
If I'm building a wonder and decide against chopping it or using a great engineer when I'm worried that the computer might beat me to it (older tech/etc).
Without reloading, I get beat by the computer, well crap, shoulda chopped/used GE. When this happens a few times, I'll learn my lesson to either chop/GE or stop wasting my time.
With reloading I'll just risk it, and if for some reason someone does beat me, I've got a savegame waiting for me to fix the problem. I don't have to ever worry about chopping/using a GE, because I can just wait to see how it turns out and load if I don't get it.
Same story for combat. I know I still lose a lot of battles with 80%+ chance to win (in fact it seems a lot more than it should be lol).
Without reloading, my SoD starts to thin out too much (or even gets wiped out), and I have to end my war early or at least pause to reinforce. Bad luck happens, bring extra units to make sure you have enough in case of bad luck.
With reloading. Bad luck happens? Nah, just reload and this time my units live. I don't have to bring extra units just in case, because I can just reload if fights don't go my way.
To me it's impossible to imagine anyone arguing otherwise. By definition, the person opposed to reloading has to be more aware of the game conditions, because if he misjudges them, or makes a mistake, it's going to be like that for the rest of the game (which is especially true for wonders).
The reloader can take all the risk he wants, if things don't go his way, he can just reload. He doesn't have to pay any attention to those finer details of getting a wonder up before the enemy, because load game has him covered if he guessed wrong.
That said, play the game how you want to. I used to reload a bunch, now I try to avoid it. I think it makes me a better player by not doing it, because I am much more careful about starting wars I'm not sure I can win, or building a wonder I doubt I can complete.
