PALcuck here.
I remember that one RPG from when I was in elementary school. Must've been like ~ 2000, 2002. The PS2 was the dankest new thing and they had one showcased at my local games store.
I distincly remember that one Rygar Action Adventure game from that era. At the same time another booth featured some RPG with battlescreens.
There was an isometric overhead perspective and the player was in some kind of labyrinth or dungeon where he was walking on intertwined passages of floating tiles with an abstract background.
I explicitely remember that whatever character was on screen walking and the first member of the fighting party had a parasol as a weapon (think it was a woman?).
This one has been bugging me ever since basically. I remember all and every other game from that time.
