My table at home is 10 x 6 in a garage. Your table is perfectly big enough for medium sized actions, the whole point of having so many soldiers to is make full use of the massive table we've built over in Crete.
Have a look on our website for the size of the table. Do you get Battlegames? There's a good shot of a third of the table with Indian Mutiny. In the next issue of Wargames Illustrated there's a big article about the centre and the table too. The table is horseshoe shaped around a big pillar, but there's room for another ten foot one edge and about six foot at the other end. I'm thinking about changing the configuration of the table for next year to give the table more playable depth too.
