Hi Manu,
I have some ideas I would like to submit for play against CPU only. The game is excellent as it is, but I figure it wouldn't hurt to ask, and besides, everything I mention can just be an "option" which can either be chosen by the user to either be used or not used (turned on or turned off).
In addition to the tiebreak thing I mentioned before, perhaps:
1) an option to edit the Stamina characteristic in the .ini so that the user can set a specific number of max accelerations (i.e. from the minimum of 5, which I think is that of the Volleyer, up to about 10, and also an unlimited option.)
2) For the Defender profile, having the user be able to set the Topspin bonus (from 0 to 20). I like the Defender profile, however I feel that the added topspin can be too "loopy" and unrealistic, even when the CPU is Defender. And since, when the CPU is a Defender, he hits a lot of topspin shots, but it doesn't seem all that realistic with the added topspin, hence the option to be able to set it to a specific value, if possible.
3) A CPU level higher than "Incredible", where the CPU hits mostly accelerations, slices, normal, and topspin shots. Right now, with "Incredible" set to 10 (highest possible level), the CPU hits a lot of softer shots when he is on the run. Maybe for the level higher than Incredible, the CPU could be able to hit faster paced shots even when he is on the run and doesn't seem to get enough preparation time. The Incredible level of TE2006 was like this, and made the CPU at that level very difficult. But at the Incredible level of TE2009, I am able to compete very well. Perhaps, even make the CPU hit even less errors at this next level in addition to having him be able to hit sweet spot while on the run. Kinda like a "Superhuman" level, but it really doesn't seem that unrealistic, since the pros in reality are like machines. As a side note: I know that I use MTRUN, but I use it just to boost the acceleration a bit. I even lower the maxspeed level down to 0.80.
Just some suggestions/options (which user can choose to use or not). And as I mentioned before, I think that the more options, the better. It adds even more variety to the great game that you have created and continue to enhance.
