Does the Diplowinn variant play similarly to the original Diplomacy?
Hello @tttppp from 5+ years later!,

I actually called my buddies up to try this variant after seeing your question as the variant looked intersting. Our game lasted about 3 hours (around a table) and was very satisfying as we often stop games around 1910 due to stalemates. It is necessary to note that Italy and Turkey (countries that usually turtle until their neighbors get invaded) were easily overran when they ended up trapped with 4 Supply Centers. It was relatively easy for England to solo the game in 1906 as he did not require too many troops to defend. And those that did, were fleets in the Atlantic which doubled as offensive fleets. Stabbing was very common in our game as you run out of nearby SCs to pick up. Based on the game we played, I would say it would be less likely to see a draw when powers such as the conservative 2-4 SC players get eliminated slowly.

I know this answer comes 5 years after your question but I hope it helps!
