Crusaders of Might and Magic is an action RPG released by The 3DO Company in late 1999 for Windows and in early 2000 for the PlayStation. It's a pretty average game for the genre and received mixed reviews at best.
The story is a fairly typical defend the land from an evil necromancer type thing. Somewhat unique for the time was that the game was completely 3D. However, relatively low polygon counts is one of the reasons the game hasn't held up that well. The graphics just don't look very good by today's standards and weren't really exceptional at the time it came out.
What I do find interesting though is the fact that the PlayStation version is better than the Windows version. While the Windows version has a pretty basic experience system, the PlayStation version is much more specific with skills for individual weapons, spells and so forth. The PlayStation version also features ways to add magical abilities to weapons that don't exist in the Windows version.
While this isn't the best example of the genre, I think it is still a game worth playing if you like action RPGs. However, I would recommend the PlayStation over the Windows version in this case. Not only will you have an easier time playing it but it actually has a little more depth and complexity than the Windows version. This game hasn't had any re-released or direct sequels though Warriors of Might and Magic is a similar style game released later for the PS1, PS2 and Game Boy Color in December 2000.
