Thanks for replying! So style does influence human players, I see. Is it possible that you make different styles vary more from each other for AI players? Because I really can't distinguish Defender, Baseliner and Puncher opponents...Is the topic "[TE4] How to improve the AI ?" still active? I may have some advice to post.
By the way, may I ask who were the representatives for each style when you designed them?
I guessed Federer stands for Puncher, Nadal for Defender, Djokovic for Baseliner, Murray for Counter, Sampras for Volleyer. No idea who's Varied.
