RyanD said:The question each publisher has to ask themselves when they create an RPG in the post-OGL/D20 world is this: Is my game so much better than an OGL/D20 option that I want to force my customers & players to pay a tax to play that game, and will those people perceive the value I'm offering and voluntarily submit to that taxation?
Whoa! Is it just me or did somebody just spill a 55 gallon barrel of hubris in this thread?!

Publishers might also ask themselves, "Is the OGL/d20 option really good enough that I want to forego trying to make something better?". In other words, it's not beyond the realm of reason to ask youself if the game design you get when you use the OGL option is worth what you paid for it.
Another question they might want to ask is, "What real proof is there that learning different rules for different games is something the consumer actually thinks about when making gaming purchases?". The only evidence I've ever seen has come directly from the entity that benefits most if such a thing is believed to be true by their competitors. Yet, no OGL/d20 game even comes close to competing with D&D in the way that the Storyteller system or GURPS do, despite their "obvious" handicap in having a different ruleset than the market leader.
