There are a number of notable differences between Western and Japanese RPGs, the most notable of which is the obviousness of linearity. In a JRPG, your quest is usually very fixed, with a definite plot and an order in which things are done. Fallout: New Vegas is Western through and through, and has poked fun at linear RPGs with a new Japanese ad.
The protesters in this poster are holding up signs that mock traditional JRPGs, with signs that read, "A game where you just follow the scenario is like living life on rails", "When did games become something that you watch?" and "I think it would be nice if the main character had a mission aside from just wiping out evil."
The answer to these complaints? Fallout: New Vegas, according to the fine marketing folks behind this poster! With its open world and focus on player choice, the game offers itself up as the superior alternative to those boring linear RPGs.
Not sure how Japan, with its love of Final Fantasy and Dragon Quest, will actually appreciate the criticism, but it's a cool poster nonetheless.
