This will be my first Final fantasy game,

Is there melee classes and magic ? or they combo of both? Do you play solo or do you have a team?

Team, but you only control one character. I can't tell you whether there's melee/mage/combo since I'm not far enough to know yet.

then what you been doing for the past 3 days? and so when i make a char? I dont know what they are for a while? that stupid... i want ot play melee

almost everything you need to know about the battle system
