First I'm sorry if my English not really that good.
Why everyone is talking about PS3 has better quality, has more appeal games, Xbox has low quality,Xbox JRPG is 2nd class, PS3 has FF,GT,MGS. Those are just small reasons. It all about being nationalistic. Sony is one of the most biggest company in Japan and is Japnaese icon that promote Japan as one of the most advanced country. PS3 is Sony product while X360 is from Microsoft. I dont see any reason why Japanese must buy foreign console when 90% of all games in both console are same and both has its own advantage and disadvantage. PS3 is better in quality, free PSN, popular brand but it was expensive, has worse multiplat games, and less JRPG. X360 is lot cheaper, has JRPG but has worse quality, less popular brand and dont have FF, MGS, Yakuza. All this make them equal. Both are great and appeal to HD gamer. So, why PS3 is still selling 4x more than X360 (i mean LTD not weekly). As i said before Japanese is very patriotic society. They always think their product is better than other countries product. Some western product did great like Ipod but that because it was lot better than Walkman (when Ipod first come out Walkman they still using disc). Japanese loves MC Donald because they dont have such thing there. Same as American film, tv series, music. All doing well there. Can anyone tell me why Japanese film, drama and Jpop is not doing well in US. ? It is just the same thing. I can conclude that Japanese dont hate American product but when their product is same or a bit worse than American they still prefer domestic product. Being nationalistic is what makes them very successful nowadays. Can you imagine if Japanese bought GM and Ford instead of Toyota when it just come out (earry Toyota is not as good as GM or Ford). I dont think it will be successful as it was now. Even if the whole world againts their product all Japanese firm can still survive if their people still support them. I think all country (especially developing country) should learn from them. In my country (Malaysia) everyone praise Japan/West product and said our local product sux. I'm agree that our (as malaysian) local product is not as good as import but if we dont support them then who will. The reason our national car is still competitive because it was lot cheaper and all import cars has lot tax.
This is just my opinion. Sorry for being quite off topic. Please dont insult me. I know some not agree with me. Everyone has their own reason and we must respect each other opinon (as long it is logic).
