i have mostly heard positive things about RDR2, i enjoyed 1 for the most part apart from those painful missions where you had to round up a bunch of cows or something, that wasnt fun at all but other than that it was very good, i have heard so much about LA Noire too
peak rockstar was between gta 3 and gta san andrea's for me, just my opinion though, i been playing so much star wars knights of the old republic, i expected it to be a good 15 hour experience, around 15 hours into it and i have not completed half of it, then i have KOTOR 2 to play so eating well atm, i just miss the gang stuff when it comes to GTA
