Axis & Allies  vs Zombicide

There are 3 different ground units, 3 different air units, and 5 different sea units you can build, as well as different support structures. Because each piece is different, the leaning curve can be large...but it forces you to be strategic and think about unit counters, which often ends up having a good blend of units

There are about fifteen different version of Axis & Allies, ranging from 1940-42 with 1st and 2nd editions of each to Pacific and Europe editions.

There are additional sets available ranging from new survivor cards to different enemy miniatures, more game tiles, etc.

There is also a medieval version - Black Plague - which offers an alternate settings and slight rule/weapon changes.

Prison Outbreak, Toxic City Mall, and Angry Neighbors are all expansion packs you can add to the base game. Extras such as Dog Companions, Zombie Dogz, and VIP (very infected people) add new figures, figures, and equipment. There is also a new version: Black Plague which takes place in a medieval setting (expansion coming in June)

The game comes with a bunch of miniatures, all molded out of plastic and have nice detailing as well as individual looks. The cardboard game cards, etc also have a solid think feel to them as well as colorful and illustrative art printed on them with the cards even being double sided. The amount of pieces and the quality of there craftsmanship definitely give a feeling of robustness that earns the game its high price ($89 retail).

Teamwork is essential to completing your objectives - some players will level up towards ranged combat, while others move about quickly. Not all players will be able to open the required doors, and you level up individually but don't let one player level up much faster than the others - zombies seem to thrive off success.
