Yahtzee + Risk: Idea Phase

This idea came up while playing Yahtzee. We wanted more, but desired to preserve the quick fun gameplay of Yahtzee. I believe it will be called Yahtisk.

Main Mechanical ideas:

Rolling for units/actions

Each player will have a faction board. This will consist of what would be the top half of the Yahtzee sheet, but for each number there would be a different unit type.

(1) Infantry
(2) Armour
(3) Air
(4) Naval
(5) Fourification
(6) Defenses

It would work exactly like Yahtzee. You will have 6 (instead of 5) dice and you will have 3 re-rolls to try and produce units. You will then choose which unit to produce (similar to Yahtzee where you would choose what number to count). You would then gain the number of units equal to number of that unit number you rolled.

Each unit would have a basic ability, defense/attack, and movement restrictions (Infantry are the only units that can establish fortifications, Armored units must be targeted first while attacking, Air units can travel on any terrain, etc.). There will also be three units that have a special ability which will be different for each faction board (Special Ops Infantry has +2 attack vs. Infantry; Bunker Defenses can only be attacked by armored units, etc.)

I think on a turn you would have a required action (Like in Yahtzee, you have to mark off something) and optional actions (Use left over dice not "scored" or used). The above would be your required actions and your optional actions could be:

Place 3 units on the map (use 2 dice)
Reveal 1 location (use 3 dice)
Move units 5 spaces (use 2 dice)
Attack a location (use 3 dice)
Capture location -infantry basic ability- (use 3 dice)

Map creation

Instead of like risk where you have a board, I was thinking about having the map change every game with location cards. The cards would have two sides: one plain side (three standard "country" spaces) and a capital side (two standard "country" spaces and one "capital space that gives you a special unit/action). Each player would have a random starting location. Players could reveal locations in any direction by placing a location card anywhere around a location where ever you have at least one unit. After every third location revealed you may place a capital. After you reveal three locations in a straight line you will choose which player to connect to. This idea is still under construction.

The capitals would allow you to start developing the "bottom half" of your Yahtzee board essentially. This will provide more interesting ways to organize your dice which will allow you to produce diverse units and execute better actions. (full house = move 2 units then attack; 3 odd numbers = helicopter)

Abstract Theme

Even though I've been explaining via military (Risk) terms, I actually want this to be more abstract with a somewhat lighter theme. I have no idea what it would be.

-----------------

Has there been anything done similar to this? Any ideas for a theme? Before I pursue this further I thought I would turn it loose to the community. It is not at the forefront of my designs, but it is definitely something I will work on. Let me know!
