Just to point this out: But 10 times wouldn't be that much of an exaggeration. Most sources claimed the average PS2 game to be $5-$10 million, and we have plenty sources for MGS4 at $60 million plus...

He pulled the number out from where the sun doesn't shine, it was fairly off topic, and only meant to bring people down who are happy for a game's success.

Ain't trolling, but it's not the best way to post either.

 For the exception that Metal Gear Solid 2-3 were more expensive than the avarage PS2 game. I thought HK stated that MGS2 budget was more than 10 million $ and I think he said that on the Making off DVD's.

Don't count on too many more new MGS4 sales in JP. Looks like stores are already flooded with used copies.
Note this is what stores are paying YOU for a used copy, not what they are selling it for.

While in Tokyo for TGS, game site Siliconera tried gauging lasting retail shop interest in MGS4: Shinjuku shop Tsutaya is offering ¥500 (US$4.88). There's one word for that and that is "ouch". For comparison sake, the same store is paying ¥3,800 ($37.07) for Cross Edge, ¥1,200 ($11.71) for Dynasty Warriors: Gundam, and ¥2,500 ($24.39) for the almost three-year-old Animal Crossing: Wild World.
