I've been waiting a long time it seems for a Civ game to look as nice as Civ 5 is looking, and I really dislike the thought that if I were to play Lan games that the animations have been ripped out of the game, while many people like to quote that the graphics are not important and it's the gameplay that matters, I'm a firm believer that it's the entire package that matters.
Please add an option to turn them back on and let the user decide if they are slowing down their game too much, and or fix it so that they don't slow down the game too much, perhaps skipping frames or something like that in the animations so that they are still there and still look good but perhaps that would be enough to make them usable in MP.
I'm the odd man out, I don't subscribe to the 'a completed game is better than a non completed game', I am of the mind that it's not the end result of who won or lost, but the fun that I had along the way. As you might be able to tell, I'm not competitive, I play to have fun and if my playmates have to run off to go get their grandmothers some chicken fingers for dinner and have to leave early with our game unfinished, I'm fine with that.
Options are rarely a bad thing in vidoe games The only downside that I see to having it as an option would be that people tend to complain because they want all options to work on their computer and their game, but that is easily countered by the community that is so vocal anyway telling them it's an option and if it is too slow for them to turn it off. PERIOD.
