Hidden Attributes
Hidden attributes are just as important as the other skills. They are hidden because they are intangible, natural attributes, which (for the most part) don't change over time. You may find hints to your fighter's level in each of these attributes by analyzing fight commentary or watching how fast the train.
Intelligence - Does not change through time. This is their natural intelligence and will dictate how readily they will change their game plan during a fight, if they are losing. An intelligent fighter may also recognize when his opponent is hurt and will go for the kill when appropriate.
Experience - Changes through time. Has a similar effect to intelligence.
Heart - A fighter with a big heart will be TKO'd less easily. They will also become MORE dangerous if they are hurt.
Chin - Maaaaark Hunto des! Good chin = difficult to KO.
Injury proneness - At present, the only injuries in MMA Tycoon will happen after a fight. If you get injured, it will negatively affect your performance during fights.
Self confidence - A more self confident fighter will have a tendency to move forward. You may wish to counter this using tactics.
Cuts - Cuts happen during a fight. If they get too bad, the fight will be stopped by TKO (cuts).
Fast Learner - If someone is a fast learner, they will train more effectively and go up in skills more quickly. This is something you need to pay attention to. If you're training someone who just "doesn't get it", then they will improve so slowly that you're basically wasting your time... if you get that feeling, you're better off releasing your fighter and diverting your attention to someone new, who has more potential.
Natural KO - Some people have huge muscles but punch like a 12 year old girl... OK, well maybe that's pushing it a bit but your ability to KO someone does not just depend on your strength - there's something intangible in there too. In MMA Tycoon, this variable is it.
The maximum value for these hidden attributes is 150.
