first, you said wuwa to dull while saying it’s similar to GI. Then it’s like saying GI also dull while denying with your own word
second, wuwa has distinct story which post apocalyptic modern with realistic touch while GI has more vibrant and fully embracing cartoon style. Which make it different for WW and GI
third, the “dull” effect you mean is the post apocalyptic theme WW brings in the story. If you mean that word for overall graphics. If you said in terms of gameplay WW has better mechanics and animation than GI.
Fourth, it already taken alike for JP players to like WW from PGR based on their experience with that game
fifth, JP region were second highest in terms of WW revenue lead by China region
