The One-Hour Wargames rules by Neil Thomas assume armies have 3-6 units each of which is 4-6 inches wide and fight it out on a 3′ x 3′ table. My Big Bases are 8cm, so roughly 3 inches wide. What to do?
2′ x 2′ Table
It seems obvious to reduce the table from the suggested 3′ x 3′ to a 2′ x 2′. Particularly since I have 2′ x 2′ tables and I don’t have 3’x 3′ tables.
This reduction in scale suits my Big Bases perfectly. 8cm is about two thirds of of the recommended base width (4-6 inches).
The only change to the rules is to reduce the distances (movement and ranges). Multiply everything by 2/3, so 6″ becomes 4″, 9″ becomes 6″ and 12″ becomes 8″. These are the main distances used. Occasionally a 10″ measure is used; I’d say use 7″.
4′ x 4′ Table
As I said I don’t have a 3′ x 3′ table so another way to go is to increase the size of the table to 4′ x 4′. I have one of those.
I’d have to use two of my Big Bases, side by side, to keep the unit size in proportion to the table.
I’d also have to increase distances (movement and ranges). Multiply everything by 4/3, so 6″ becomes 8″, 9″ becomes 12″, and 12″ becomes 16″. Again 10″ causes a slight multiplication problem; I suggest using 13″.
Just play the game
Okay, I could get a 3′ x 3′ table and just use my Big Bases as they are. The units would be slightly under size but nothing major.
A common feature of all the One-Hour Wargames rules is “units are eliminated on the acquisition of 15 hits.” 15 hits is a lot to track. A quick google suggests people use a bunch of dice behind the unit to track the hits. Of course you’d need up to three dice to get to 15. I imagine it gets a bit messy when several units have several dice trailing along behind them. And quite easy to knock one or two dice over in the process and hence forget how many hits the unit has taken.
As it happens I just got some Casualty Markers from Commission Figurines (Code = MAR12). They should do the trick nicely. I’ll only need one or two tokens to get to 15. They are also resistant to bumping over.
