2.) Career mode is so much fun, especially when you play visitors online and it has a lot of great paths you can but stays the same at the end, what I meant is either you want to increase your stars or train more.
3.) Very fun and absolutely gorgeous especially when you play online and play better players than you. Hah.
4.) I won't say different strategies but it's more like "techniques" on how you'll approach the opponents to know when you'll put out the drop shot, where you'll make them run, and how you're going to put out you're next shot.
5.) I'd say hard on arcade mode and when you're on the 2 stages of your career mode because the King becomes a beast mode but later on when you get use to the game, you'll beat him pretty easily and he might not even score. (Beat him and love him the 3rd time in career mode, the second try I almost but he's just really good and my stats are bad.)
6.) That's a great deal, I think it became one of the purchase on PS+ but that's already a good deal. I bought mine since its release.
PS: Good luck and I hope to see you online if you ever bought the game!
