I dont. i hardly ever load, but when i do it, it doesnt bother me. in fact i rather load then live with the frustration of knowing "if i would have done that, well, that would have worked". i dont start a new game for that, if i just spend 4 hours getting this far. I reload if i miss a wonder by <2 turns and can get it if i chop that last piece of forest with 3 workers. I also reload if i loose a lot of units in a single turn due to some bad rolls in a row. like 10 attack units with all 70%% chance and losing 7 or 8 of them. doesnt happen often, but when it does, i reload. i think it bothers civvers more maybe because we want the game to have a certain amount of realism. many mistakes were made throughout history and dealing with them and surviving is part of it. the game can reflect that. Personally i hate it when mistakes kill a good game, so using the time machine and loading the game a few turns back isnt cheating in my book. thank god the AI cant do it though.
