1st request, well the only file u have to edit is EDU(not 10 files), if u change the upkeep cost, and as i said, its not a big difference from what it was, only the knights upkeep that should be tweaked. as an example;
stat_cost 1, 1180,
480, 90, 70, 1180, 4, 200
stat_cost 1, 1180,
280, 90, 70, 1180, 4, 200
dont need to do much more then this(this is dismounted gothic knight).
2nd request, it's not really hard to make a second weapon, just need to change the second weapon stat;
stat_sec 3, 2, no, 0, 0, melee, melee_blade, piercing, sword, 45, 1
You can copy this line above, to all the pikemans, and balance the damage depending on what unit. you dont need to change anything more then this, to have a second weapon..
Would have done this my self if the game didnt crash, everytime
