As much as I really like the game, it's tiring to play. I'm hearing now that they're looking to do a few sequels for the series, but honestly I think they should leave it alone and maybe do a more detective game set in either 70s San Fran, 50s Vegas, or modern NYC. Another "Noire" game is just going to be more of the same and take away from what they did do remarkably well with this entry.
I concur and would go on to say that I would much rather play a game like this set in Las Vegas in the 50s than Hollywood. So much more possibility for corruption and murder and mob ties, plus it's Vegas, who doesn't love Vegas?
