Two fighting modes, SD Hiryu and Virtual Hiryu, are offered in Flying Dragon. The SD Hiryu mode, which features super-deformed characters, the combat is much simpler, and is where the RPG aspects come in. You play in tournaments and when you win you get items. These items boost your attack, defense, heal you etc. You will also find treasures and spend the money you won, to the shop and buy other items.
The Virtual Hiryu mode is the supposed more realistic fighting system with a more of traditional 90s 2D or 3D fighting (you choose) with a solid fighting engine, long combos etc. The 2D mode doesn't feature a rotating background or sidestepping, whilst the 3D mode does include sidestepping as well as some extra special moves.
Opponents are really tough. But fortunately, magical items will appear after you fulfill certain requirements like winning a tournament by getting time over in 5 one round fights with the time set to 90 for example.
Controls are easy and incredibly easy to learn. A simple move is just a couple button presses.
Even though Flying Dragon is not very original it does contain a lot of fun things from other fighting games, items, stocks, super/ultra moves, different styles etc.
Graphics are not its strong point here, but they are adequate for this type of game, although I would expect more from the developers due to the graphic's power of the N64. Different background graphics and character models were included for both the SD and Virtual Hiryu modes. The polygon models are simple and have a limited amount of animation though, and no special effects were used to take advantage of the N64. More on that the backgrounds look quite cartoonish and there are no animated scenes on them. They tend to be drawn in 2D and zoomed in and out as the camera rolls (in 3D mode!).
The sound is of the same standards too. The sound effects are good, though maybe not that realistic and the voice acting is not stellar. Music fine although the sample quality of instruments doesn't sound that good.
