iwould like to say 2 things i have just rememebered now:
1: could u alter the npc reps for the ASF/CSF? so that if u attacked them, the bases and jgs around u would not get hostile.
2: could u possibly open up so jump holes/gates from SP? like the hokkiado-tohoku jh, chogoku-tohoku (for some reason u can go from tohoku to chogoku, but not back) NY-alaska and sigma 13-new berlin
just some suggestions
