"I am playing L.A. Noire now. I love the game.
Honestly, I don't know how buggy it was at release, but now, patched up good, I haven't run into anything yet, and I dare to say it was worth to port it to PC. But was it worth ditching the RDR porting for L.A. Noire? I don't know, one should decide that for her- or himseIf."
LA Noire, to me, is one of the most underrated games of all time---the facial animations, the voice acting, the setting of historical Los Angeles---its like a work of art, IMHO. Don't get me wrong---I've played Red Dead on the X360 and loved it, but I like Noire more.
And yeah, the PC bugs of Noire were pretty bad when it first came out---the framerates were laughably bad---but other than the issue of being locked at 30fps (apparently an artistic choice and not a bug), all of them seem to have been fixed.
