Royal Blood came out for an impressive list of different platforms (at least six, including the PC-98) and is conquest game with some battling elements when you invade. Although it's quite worth noting your wizard hero is a lot stronger than the average soldier, and the battle ends when the other players fortress is occupied.
Control is via the mouse, and saving will write to the second disk drive, which can be either the original Data Disk B (You won't see the intro after doing this) or the provided user disk. This game had a sequel, but it was a later windows release rather than for the PC-98.
