This is my last comment on Gray Matter:
Gray Matter had a huge amount of hype prior to release and was thought by many to be the next big adventure game. The game was released to luke-warm reviews and disappointing sales.
The fact that Prof. Layton has large marketing and production budgets shows you that adventure games are indeed mainstream. LA Noire also has a huge budget - both production and development. This makes it - an adventure game a mainstream title - and it has had huge sales and stellar reviews.
