Twoy's thoughts on Siege, taken mercilessly from the other thread. Please use this thread to discuss siege and any other significant rules, and if enough of you like a set of rules, we might even officialize them.
Type 1: Siege Tower
A Siege Tower has move 1 and Attack 0. Maximum holding capacity is equal to its hits. Only units with 6 Hits or less may use a siege tower. Defending units engaged by units inside of a Siege Tower do not receive a fortification bonus. The cost of a siege tower is according to the normal rules. Required specials for a Siege Tower are Siege (Cost +10) and Container (Cost +2/unit).
Sample Siege Tower:
Move: 1, Hits: 7, Att: 0, Def: 5, Cost: 38, Specials: Siege, Container 7. (Note: Container 7 cost 14 points)
Type 2: Battering Ram
A Battering Ram has move 1 and Attack 0. Units using a Battering Ram must have at least 4 Heavy Units (Greater than 6 Hits) to use a Battering Ram during an attack against a fortification. Defending units inside a fortification engaged by units using a Battering Ram receive a negative to their fortification bonus equal to the Battering Rams Battering Level. The cost of a Battering Ram is according to the normal rules. Required specials for a Battering Ram are Siege (Cost +10) and either Battering 1 (Cost +10) or Battering 2 (Cost +20).
Sample Battering Ram:
Move: 1, Hits: 5, Att: 0, Def: 5, Cost: 37, Specials: Siege, Battering 2.
Flying units may not use siege weapons of any kind. Defending units inside a fortification do not receive a fortification bonus to defense when attacked by a flying stack; however, defending units inside a fortification with a tower receive a +.1 leadership bonus when attacked by a flying stack.
So, there's that set of rules. Or, we could give walls hits, let Battering Rams and Siege Towers and Assorted Other Units (e.g. Battle Bears) attack the walls, reducing the hits, and we let your units in at some arbitrary point in time.
