i have now done about as much of Phantom of Network's postgame as i really feel like (all BBS requests complete, more than enough battlechips to reach the deepest part of SecretArea 2 but not ground out enough to get all the battlechip completion stars, fighting CacheEX and both SecretArea Bass iterations). pretty sweet i think, glad i did it and saw the sights and stuff. might go back to give the virus busting ranking a shot or maybe to finish up the grind for the missing library slots and pick up the rest of the items i might want... but yeah game remains good and you really should play it!!
(i'm not playing bn4 next i'm pl;aying LON next its just that pon takes place before it)
