Yeah, it turned me almost crazy to discover by myself how the speed-walk works in this game.
I think the Sonic!/Camelot guys were just experimenting, being this the first Action RPG they ever did: their previous "Shining" games were Tactical RPG games (which are AMAZING, I love those games, while I really hate and detest the "Fire Emblem" series, which are basically the Nintendo Tactical RPG counterpart... and I don't even know how this is possible ¿?), and Dungeon Crawlers (which I played a lot less, but I found them Very Good).
In any case, Shining Wisdom is not the best game of Shining series... they put a lot more effort doing Shining the Holy Ark and Shining Force III trilogy for Saturn, for sure. But I'm not sure it deserves the worst Sega game... Love its manga boxt-art, though.
