Quick Jump: Summary of all changes

Introduction Edit

The Multiplayer-Evolution ruleset ("MP2") is the newest ruleset in the Multiplayer-branch. It takes advantage of new features and improvements in Freeciv 3.0 server in order to create a radically improved and modernized completion to the MP ruleset branch. MP2 greatly improves: balance, strategic diversity, tactical depth, early-game Sea units, and late-game Air units. Over a two year period, many contributors vetted and balanced many other changes whose aim was to faithfully follow the principles in the MP2 Manifesto. The short version of those principles is: improve balance and increase playability, strategic diversity and depth, creativity, realism, fun, and overall richness. Enjoy!
