The benefits are two days with a greater amount of space than I am able to offer.
So, I have two games that would fit this bill, both of them WW2 spearhead.
Jon, Mark and myself have played this before. An early war British v Axis mini campaign in the desert. Simple campaign mechanics along the lines of the Malayan campaign. The battlefields are played on 8' x 6' tables and the benefit of the club is that we can play two scenarios back to back with the aim of getting four games played in the weekend. Rules and figures ready to go.
The Road to Berlin
This is a large single battle played on a 10' x 8' table featuring autobahns and entrenchments. A Soviet shock army v a weakened German Korp comprising Volksturm and elite Panzer instructor units. The last gasp of the Third Reich featuring aircraft, tanks and huge Soviet artillery strikes. I suspect between us we have a lot of the troops and terrain but we may have to make up a few specials and get hold of an Autobahn including bridges that can be demolished.
Have a think and let me know what you think. It may be that we are missing out on adding another dimension to our gaming.
