Rockstar's epic detective caper L.A. Noire sold 899,000 copies in the US during its debut month on sale.

While that doesn't sound too shabby to us, industry analyst Wedbush Securities isn't impressed.

Its monthly investor report noted that the game's performance was "below our estimate of one million units".

The game, which scored a sturdy 8/10 from Eurogamer last month, topped the monthly NPD sales chart, as reported last night.

Michael Pachter's employers had kinder words for Valve's Portal 2, revealing that the game sold in excess of the 200,000 units it had anticipated for its second month on shelves.
