Ki-84 is my first choice...
but I think we need all the single engine army fighters
Type 1 Ki-43 Hayabusa
Type 2 Ki-44 Shoki
Type 3 Ki-61 Hien
Type 4 Ki-84 Hayate
Type 5 Ki-100
and two engine fighter
Ki-45 Toryu
for the Navy fighter, maybe the
J2M2 Raiden
and of course we need bombers...
Betty, Val...
oops it was supposed to be one, but my wish list is kinda long <G>
