It was the best of times, it was the worst of times. Here is the Metal Gear Solid 4 tale of two regions. In Japan, Famitsu reports that MGS4 sold 476,334 copies in its first few days, becoming the best-selling PS3 game to date in the region. Snake also boosted sales of the PS3 itself, with Japanese sales hovering around the 10K mark; the console sold 77,208 for the week.
The UK tells a slightly different MGS4 sales tale. MGS4 is the second fastest-selling PS3 title behind Grand Theft Auto IV and was 14,000 short of MGS2's initial sales in 2002. Although the UK's Chart-Track apparently did not release actual numbers, the company's director did say that MGS4 had a "minimal impact" on hardware sales and that "there's not a lot to say about it."
Unless Sony or Konami sends out a release, we're not expecting US sales figures until NPD's June report releases sometime next month.
