Getting back on topic and now that I think about it GT5 is somehow similar to Medal of Honor(2010).
well,MoH as a rubbish campaign mode,made by a different developer which makes that bit of the game horrible(danger close),but the multiplayer in MoH is made by dice and its actually the best that I have in shooters in the last couple of years,multiplayer in MoH is incredible and people are missing that,due the rubbish campaign,a part of a game can kill the game itself,but a good bit could make it good,I think this is the case of GT5 ,GT4 HD is the campaign on GT5 proper is the multiplayer if we put it into perspective with MoH.
Same case but initially MoH did good sells due to its publicity campaign so is down to how a game can be advertised and how regular players can get the good side of these games.
But since GT5 focus mainly on advertising the "good" bit instead of the "bad" bit people will probably end up taking the 800 standards issue as something common,I'm starting to see that over JP public,not like +800 standards but more like 800 "whatever" cars with no wheel changes and no interiors,and 200 "must have" premiums,so its all down on how the public sees the product,and trust me on this JP are not stupid,that's for sure(BTW I'm not Japanese so I'm not over flawing myself).
