Wizardry 8 is a must-own CRPG. It is on its own, the last Wizardry game of the Dark Savant trilogy made by Sir-Tech as well as being the last within the official series (the license was given to game developers in Japan who made their own Wizardry games such as Tale of the Forsaken Land which have their own story and universe in comparison to that of 8).
The gameplay itself gives players either a turn-based approach or a more active but still turn-based take on combat. The game itself is a mixture of fantasy and sci-fi, pitting players against mundane enemies such as a human spell-caster and giant rats to more technological or magical enemies such as androids or demonic beast. Wizardry 8 offers a variety of customization to players based on the races and classes to choose from. This means one can play with a normal party such as a dwarf fighter, elf mage, and a human thief to something a bit more diverse such as Hobbit ninja's and Felpurr samurai's. Not only is there a variety in races (such as human, rawulf, dracon, mook, etc.) and classes to pick (such as bishop, priest, ninja, alchemist, etc.) but the game also offers a variety of equipment to use, each with their own advantages and restrictions.
The story of Wizardry pits the player's party against the forces of the Dark Savant for whatever reason (using an imported save where you went with an important NPC to Dominus, following a prophecy you'd first hear a bit from the Trynnie merchant, the game does have different intros based on what saves you use, be it imported saves from Wizardry 7 or using an entirely new party). Ultimately (without trying to spoil too much), the story would lead to players trying to gain a power that the Savant himself desires.
The only con to Wizardry 8 as far as I know is that trying to play it off Steam with a mod (only tried the Christian Coder mod) doesn't seem to work for some reason.
If you are a sort of person who is interested in playing a good CRPG that is worth the time and money spent, Wizardry 8 is one to go with.
