However, when all the majors have four chits invested in Trench Warfare tech, they start to reach Trench Warfare tech levels 3 and 4 by mid to late 1915. It might be interesting to experiment with a house rule limiting the number of chits players can invest in Trench warfare tech to 3 or even 2, to see how that affects the tempo of the game.
telescoping
Yes, I think this is true for a lot of the Techs. I have just adjusted my Mod for my next game against the AI by reducing the maximum number of chits that can be used for any Research category to 2. As quite a high proportion of games in MP seem to be decided (if not actually finished completely) by the end of 1916, it would be interesting to investigate ways of extending the conflict into 1918, so things like US participation in the war and the Kerensky period in Russia in 1917 became more regular features of the game. I think a lot is being lost through the telescoping of the war into the period 1914-16.
