I love 8ing fighters, their basic motion and impact animations are so deeply satisfying that playing them even at a casual level is always fun. Esoteric, demanding, and the community's microscopic, but great fun anway.
The level of depth on display here was genuinely frightening, but it's fast and rewarding to a tee. The systems are really easy to understand, the characters feel varied...Unlimited Codes is well rounded and hard to really criticize too much aside from the usual fighter gripes of Arcade Mode boss difficulty being stacked pretty high and unlockables coming at a pretty slow pace. If you're a Fate fan or looking for a new fighter as a genre vet then this is a good one to try out, but otherwise there's not a whole lot to draw in those outside of the fanbase.
Very graphically impressive PS2 game. However, it was very lacking in multiplayer content. There aren't many characters or stages, and inputs for supers felt pretty inconsistent. It could be a 3 star, but I didn't like most of the characters I played, and considering the small roster, there were 3 characters total I really liked.
