Clock Watching For Improved Gameplay?
Thanks to GamerDad for their editorial discussing the use of a PC/console's internal clock to drive gameplay. The article starts by looking at GBA title Boktai, which "...knows what the time of day is and adjusts the onscreen graphics and gameplay to coordinate with the conditions", and also applauds "...a number of notable games that have used the internal clock in a console to either drive gameplay or allow for timed release of features", referencing Nintendo's Animal Crossing in particular. But the author also advocates simpler time-based rewards, as used in titles like Ikaruga: "Instead of having all the goodies that come with repeated play be unlocked through tasks, how about releasing some of those things dependent on how many hours you spend playing a game?"
