Pre-game options: number of AI, map size (Small / Medium / Large), and lobby countdown
Promotion / demotion screen when your rank changes
Pause in singleplayer
Hover the Population and Gold counters to see what's driving them
Research queue + a notification when a research finishes
Building shortcuts (keys 3–8) and Shift+click to attack, even by sea, without opening a menu
Ranked rating reworked to be much stricter: climbing is earned, losing actually costs, and the very top is reserved for multiplayer
Everyone now starts at 500 and climbs from there (existing ratings adjusted to match)
Research cost is always shown now, even when you can't afford it yet
The AI now builds factories
Smoother map coastlines
Building prices no longer explode into the billions on large empires
Map coastlines no longer look pixelated
Rank names are now translated in every language
A multiplayer game needs a second player to start, for a bots-only game, use Solo
