I also bought a hardcopy a few hours ago still deciding whether or not i should rip the plastic cover off and install it or take it back and a refund such a difficult choice.I bought it hoping its gonna be another totalwar masterpiece but judging by some of bugs/glitches said about on the total war forum i dunno.
I have no doubts at all that it will be another totalwar masterpiece (its already my favourite totalwar), however a lot of people are experiencing issues with the game (not me personally) so it might not fulfill its role as a totalwar masterpiece until a few more patches come out. All you need to ask yourself is do you want the game now and put up with any bugs you might encounter until they are fixed, or would you rather wait 9 months and then get the game. Up to you.
