ReRolls

Seems simple and straight forward. $10 seems good too.
I wouldnt use it though, the game is long and complex enuff.

Kinda agree with bob. I have in my game Generals give a piece a reroll for first round only and any were from 1-3 pieces. Some Generals will give a reroll for 2 tanks.

Pain State,

Very interesting House Rule idea. I like it in spirit. I’d want to limit this a little bit though. I see this as another balancing tool. It might be that the US is the country that could mostly afford this cost.

1. I would not give tokens to majors. They have to pay for them or never get one Period. It will demonstrate how IMPORTANT a re-roll token really is to a player. However, each minor nation would get 1 to start with except France. ANZAC, China, and Italy get 1 free token otherwise they probably would never get 1. Costs for a Re-Roll token still remains at 10 IPCs. I agree with that. Purchased re-roll tokens would not be effective until the next turn (just like you can’t place units on a Factory until the next turn).

2. Regarding your house rule, do you re-roll the entire battle or is it like you re-roll your 2nd roll in the same battle if your dice missed, then re-roll your 2nd round? I would agree with the first portion of my question, but not the 2nd. For me, it would havve to be the entire battle re-rolled (for both sides). Not just the side using the re-roll token.

Re-rolls or Extra rolls?  A re-roll has advantage of seeing the initial result.  I would make the cost $5, with use as a re-roll hits on a 1, or extra roll hits on a 2.  Can be used anytime.
