Cracked.com, one of my favirote site right now, published a story last week named “The 4 Worst Thing About Writing For The Internet” . It’s a great read, and a the same time, you could apply all of the four things to making games, and it would be just as valid.
I don’t want to ruin their article, so go read it, and then come back and tell us: have you had all the same experiences with your games? We have.
