Having finally received the game last week and after playing a LOT of hours I think this is probably the best/most emjoyable game I have in my collection. However it could be even better if 2K could do something with the following (now this is from my own experience, so everybody is free to disagree):
Gameplay experiences:
* Serving is too big, especially if you have high stats on serve and power combined with extra serve abilities, there's way too many aces if you play against someone who knows how to place a ball. Even if you can still win these matches, they are NO fun to play. I would like it if 2K got rid of the extra serve skills or if they would just make it WAY harder to exactly place a serve on the lines, make it so that even the best servers can only get to about 65/70% if they go for the big serves on the line, also second serves hit with this much "risk" should even be harder to make.
* Too much power; if you play someone with 90+ power, there's not a whole lot you can do about that. I think that it should be a bit toned down and also make people miss way more shot if they go for a power shot from difficult positions on the cout. Now if you can just get to the ball it's always possible to go full power and almost never miss a shot. Make this harder for difficult to reach shots please.
* Lobs too easy; lobs get almost never missed, even if you try to hit it from an almost impossible position, which is too unrealistic. Please make the timing harder on this.
* Angles are too sharp; I do like the idea of being able to hit angles to move your opponent out of court, but hitting balls that arrive very hard to you with you standing behind the baseline, it should not be possible to hit shots that are almost floating parallel to the net, this just can't be done in real tennis and though this is a game, please a bit more realistic.
* Fatigue should play a bigger part; now there is too much recovery, especially in 3 and 5 set matches the player should get more tired if they have low stats on stamina. Now recovery is too big and you don't get punished enough for having low stats on that part. Also, especially if you play the CPU, even though they don't have any more gas in the tank they still get to almost impossible to get to balls. Just make it so that you CAN reagain fitness, but only by tanking or making the rallies shorter.
* adding the lob volley, not in the game yet and would be a nice addition
* More errors; with bad timing you should miss more balls. Now I realise this will scare away the more arcade/ Virtua Tennis players, so maybe add a SIM option or something
* Footwork glitch (already being worked on so no further explanation needed)
To sum it up, just want a more balanced gameplay; when 2 players of the same quality play against each other 10 times with both having players with different styles/strengths, both should win about 5 matches. Any style should be able to beat any other style.
Other aspects (maybe for Top Spin 5)
* much better Move implementation
* animated ballboys
* linesmen ducking away when balls get fired at them
* Challenge system
* true to life service motions from pro players
* Save replay option
* More stats (fastest serve/ average 1st and 2ns serve, slowest serve etc)
* breaking strings (if you play a lot of top spin shots for example they should break more easily), with you being forced to move up to the net to end the point
* Ability to turn off the auto swing/auto movement
* add Wimbledon and other real tournaments
Tell me how you guys think about this or add your own remarks/ideas!
