I have played most of the tennis games out there and all the most recent (Top Spin 4, Virtual Tennis 3, and This)...
I enjoyed the gameplay in this game more than in any of the other games. Everything is done with the right stick just like most of EA Sports other games.
The graphics were about the same in comparison to Top Spin, (VT3 is worse). One thing that is alway cool though is the game face element for EA Sports games where you can import a picture of you to get an incredibly realistic character face. I personally was a little disappointed with the graphic though. I expect EA to have the best graphics, and they were just good. Characters look very real, but everything around them is very sub-par.
Now the game features, is pretty bad. It just has you train, and play in tournament to ultimately become the number 1 ranked person. I felt like it got boring fairly quickly, (about 2 seasons). It is way too unrealistic with the rankings. You can win every masters for 2 straight years and still be ranked 35th in the world. Seems a bit ridiculous.
Online play was really fun though. Everyone is really good on it though, so wait a little until you try it out. Good game over all, could use some new features to make it a lot more entertaining long term, but hey... this is GF, that stuff doesn't matter here. Definitely a rent though, and not a buy.
I just got this game on the 17th of February. I like this game. It's hard to determine if this game is better than the Top Spin games, but so far I'd say they're both good. It's harder to hit power shots in this game and I feel like I'm playing an arcade game!
