1940s crime thriller L.A. Noire and eastern European swashbuckling adventure The Witcher 2 are shaping up to be two of the biggest games of the next few weeks and, potentially, of the year.

Europe: May 20, 18+, £45 / €59

Another sure blockbuster from the Rockstar stable ( Grand Theft Auto, Red Dead Redemption) and noted for its characters' tremendously lifelike faces, L.A. Noire is lighter on gunplay and with an emphasis on investigating crime in 1940s America.

Premium Edition, $49 / €49 / £35
Collector's Edition, $129 / €99 / £89

Expect an engrossing, detailed romp through medieval eastern Europe from this promising sequel. Graphically impressive, carefully crafted, and with combat balanced by brain-teasing moral choices, preview material indicates this could be one of 2011's finest.
