First of all the screen shot has absolutely nothing to do with the system itself. But hey, people aren't suposed to rate by the screeny anyway. Second, I can sum up my feelings for this system in only 3 letters. "OMG". As in: "oh my god that f****in' rocks. I wanted a turn based battle system for so long, I'm glad someone finally made it.

I would have taken a different route and used the multiboard for an interface and the arrow keys for navigation, but this works so much better. Tare still problems of course (this is more like pre betta stage, no offense). You should change the "my spell book" to something that doesn't have move or attack commands (disable all attacks, set movement to 0 and turn rate to 0, or .10 if it won't let you go lower) then change the model to the same model as the player unit, and make the name the same as the player unit. Change the spell book to a non-hero unit and make it so every time a player selects the combatant, it selects the spell book for them automatically. These are all just suggestions of course, what you do with it is completely up to you.
Anyway, it ain't perfect, but I think "it pretty good start" is a vast understatement.

Keep up the good work mate.
