well...in GENERAL...FF games dont connect with the plot of the previous game...there are some exceptions of course...like FFX and FFX2...etc.
but it has no relationship with FF4...it a good/fun RPG...my only complaint on it is that the basic plot is kinda...well check out other threads we've dicused it about a million times now...
and WiFi features...you can send people messages over mognet...when you end enough you can unlock a total of two sidequests...
1. Gets you the the Onion Knight job after completion
2. Lets you battle the most uber powerful boss in the game...(I might add that I never managed to beat him) other than that...there are no other WiFi features...
