gosh no one does anything interesting. im waiting for someone to say they do something crazy like, uhh i don't even know, but everyone is putting generally the same thing
Fine. If you want something exciting I will make up a tale of heartbreak and joy, tears and laughter, life and death. In short, I will create a saga of the marvelous experiences that god has bestowed upon me while I waited for a game on the computer to load.
Anyways, the trend I've noticed is that most gaming companies have certain cut-scenes or sequences while the game is loading. Some provide vital level information while others just show a random sequence. For instance, on Fallout 3 your given the no. of monsters you shot, Rad-x consumed etc., while Mass Effect has loading sequences.
This obviously doesn't apply for flash games though. Since they load quite fast.
It depends where I am. At school I just wait a sec for it to load, on my computer at home I either look for a better song to play or wander around my house for a while.
