There's the obvious things you expect to see. Chocobos, moogles, cactuars, bombs, Cid, Biggs and Wedge etc
But I wasn't expecting to see Biggs and Wedge pilot an airship called the Tiny Bronco.
The salute or goodbye wave of Gridania looks like the Blitzball sign for victory, otherwise known as the "praise be to yevon" gesture.
I used a limit break and saw "Braver" show up as well as a see through Buster Sword.
There's a place called Costa Del Sol. I also saw a guy doing squats just like Cloud had to do in the gym.
Looking back on this list, that's a whole lot of FFVII going on. Do you like all the cross references? Or do you feel that it takes away from the games originality?
