It's interesting to see a game "rebooted" and head off into new directions.
It's a risky move for a game company, because it often tends to alienate people who liked the first version and it's hard to lure back players who didn't like the first version and have them give you a second chance.
Some reboots fall kind of flat, like the AH edition of Cosmic Encounter, which few fans think was an improvement over the Mayfair edition.
So the reintroduction of Wizard Kings, styled 2.0, by Columbia Games is an interesting experiment. Wisely, Columbia kept the component changes relatively small, so anyone who invested in Wizard Kings 1.0 could still use most of their stuff.
And the changes that were made were not wholesale concept re-imaginings, so players didn't need to relearn the game. But the changes were important, nonetheless, and changed the focus of the game significantly. Among the most important changes were stacking limits, the economic/build systems and the elimination of one race (the Ferkin warboars) for another (the human Feudals).
The original edition of Wizard Kings was essentially a two-player wargame, conceptually a magicked-up version of Victory: The Blocks of War. The base game had two armies, Elves and Goblins and players had the option for adding more by purchasing additional armies of Ferkins, Dwarves, Undead, Amazons and/or Barbarians; reinforcing forces of Chaos creatures with their own spells and more maps. The biggest weakness of the base game was that there wasn't really a good scenario and many players complained it seemed kind of boring.
Online scenarios soon popped up and many of those were creative and interesting. And many took advantage of the fact that there were seven different armies to play to create viable multi-player scenarios. Feeding off the resurgence in multiplayer gaming caused by the growth of euros, I think this became the preferred way to play for many people.
The 2.0 version of Wizard Kings is, at heart, a multi-player wargame. All seven races are now in the base set with small armies and there is just one kind of expansion set Heroes & Treasures, which adds two new units for each army and stickers and blocks to give each army one additional special unit such as a chaos creature (stripped of their old spells) a treasure or other item such as portable gold and silver treasures caches.
There's a "collectible" aspect to these expansions in that the exact contents are random and vary between boxes without being known to the purchaser beforehand. This is mitigated by the fact that all units are valued on the same basis in the game system without any strange rarity or overwhelming power.
The focus of the scenarios (in the base game, four 2-player battles) is now on short, sharp actions, instead of the longer, full-scale wars encouraged in 1.0. The reduced stacking and hexside limits have the effect of increasing the power of the stronger pieces because it's harder to swarm them with lots of low value units. Because the battles are smaller, there's also a bigger luck element and more chance for extreme results.
It appears that this reboot has been a success. There seems to be renewed interest in Wizard Kings. The 2.0 version seems a better match for the theme and the game's potential.
