Aye, other developers do this as well. For Monster Hunter 3, CAPCOM runs the servers itself in Japan, but contracts with Nintendo to run them in the US.
Maybe you should try some games that use a 24hour clock before judging, as I said, other games have this and people don't complain about it in those games. So what if you spend more time in one period of the day than another? Is that really so horrible? The game looks beautiful no matter what time of day you're in. It's strange because usually people around here are all about sacrificing gameplay for realism. a 24 hour clock makes it feel more real and doesn't really sacrifice gameplay. Some games don't even have a day/night cycle at all and the areas are either arbitrarily light or dark, and people don't complain about that in those games either. Some games like EVE are set in space- Space is always dark. Is it unfair that the game is always dark when I log in?What if I can only play at night most days? am I only going to see eorzea in the moonlight? Never going to see the sun rising because I'd be asleep by then? Terrible idea
It's fine though, they're not going to do this, apparently people like seeing the sun rise in set in the course of a few minutes. But It frustrates me that the only common complaint people have is one of "what if I can only log in at one time I always see the same thing." But these people forget that lots of games don't even have day/night cycles and you always see the same thing. As long as day/night doesn't have significant impact on game-play itself, I see this as but a minor issue. I understand where these people are coming from, but I feel like people are trying to make it sound worse than it really is while ignoring the conveniences of having only one time system to worry about to focus on the aesthetics.
Oh well. You win some, you lose some...
