She uses a mecha?  I'm afraid that may be straying from the theme of the series, which is about martial arts rather than tech.  You may have to seriously sell this to me.<br/><br/>As far as coming from China, either works.<br/><br/>As a side note, I'm developing a system for the game if that's the route we want to go.  I leave it to player vote.<br/><br/>You would take Strength or Speed (plus any special training mods like Strength or Speed) and then take a number of d4s equal to your Martial Arts rating... roll the dice and take the highest die result.  ie if you have Martial Arts x3 and roll a 1, 2 and 4, you would take the 4 and add it to your modified Strength or Speed rating.  For this example let's use Ranma with his Speed of 6 and Speed x2.  He rolled a 4 so he would add it to 8 for a total of 12 to hit.  Ryoga tries to Dodge with his Speed of 5 and Speed x1.  He rolls a 1, 1 and 3, so he takes the 3 and adds it to 6 for 9.  Ranma hit Ryoga with a 12 to Ryoga's 9.  Since he got 2 over the 1 needed to hit him, Ranma gets to add a +2 modifier to his damage roll.  Ranma's Strength is 5 plus Strength x1 for 6... he then rolls 3d4 again (because of his Martial Arts x3) and gets a 3 as his highest result.  He adds that 3 to his base 6 plus 2 for the extra damage modifier and gets a total of 11.  Ryoga has a Durability of 6 plus Toughness x2.  That's a total of 8, so 8 points of Ranma's attack are absorbed with a total of 3 points going to Ryoga's hit points, which are (Durability+Toughness)x3.  Ryoga has 24 hit points before he's bonked so now he has 21 left.<br/><br/>What I'll do is keep working on this system and post up NPC canon characters' stats.  If the stats they have are just way beyond what the PCs have I may give you guys some extra starting points.  It's as always a learning process.
