Top Spin 4: worth the wait and best tennis game to date!
Pros: Improved graphics and venues, Player creation mode is much more in depth, Career mode is improved (finally can play a real length match/tournaments ie. best of 3 and 5 sets with sets going to 6 games and not 3!), Game play is smooth, not too much diving as there has been in the past, new control system is similar but a bit more depth for better shot making.
Cons: Players don't have their own signature styles! This is the biggest disappointment. You would think that only having 25 players, that they could at least have put in 25 signature styles, instead there are only 4. Pretty sad considering NBA 2k11 has over 300 players and they all have their actual signature moves and styles.
All in All: It's improved since Top Spin 3 (which was at the time the best tennis game out as well). Obviously still has some things to improve, but so do most games. This game is addicting and for the everyday tennis fan and for the casual tennis fan, this game can be enjoyed alone or multiplayer!
Hope this helps anyone out who is questioning whether or not to buy this game.
