Here's a summary of the changes we've made from Age 12:

Major gameplay changes:
• Every minute you receive a game turn. Turns are used for attacking, raiding, sabotaging, and going on conquests. Attacks cost 150 turns, raids cost 25 turns, sabotages cost between 1 and 5 turns, and conquests cost 10 turns.
• Raids steal less gold than attacks, but cost fewer turns and cause the same damages and casualties to the opponent.
• Upgrading your Economy uses Experience to increase your labor force and give you a greater income
• Researching Technology uses Experience to increase your military stats.
• Conquests are the quickest way to gain Experience, but other actions which cost turns also give you Experience. Going on a Conquest against stronger opponent causes more damage, but gives you more gold if you are successful. Conquests that you have done many times give you less Experience.
• Income is also distributed once per turn. Soldiers generate one gold per turn, and 10 covert troops generate one gold per turn.

  Sabotage changes:

• Limited the amount a player can be sabotaged per day
• Adjusted minimum ratio of spy:sentry required to sucessfully sab
• Adjusted the sabotage formula - in some cases it will now be easier to sabotage, in some cases it will now be harder, and a sabotage is never guaranteed to be successful! Additionally, it should now be easier to get into an enemy's armory with well-trained spies, and there is less penalty for sending more spies to do more damage
• More levels of covert skill are available now. Each level has a reduced cost and increases your ratings by 60% per level, instead of 100% per level.

Other gameplay changes:

• Active officers who have logged in within the last 24 hours now also help to increase your ratings: The first five active officers you have add 10% each to your ratings and damages, and any additional officers at 1% each up to a total of 2x maximum
• Players may change their race up to 3 times during the Age. Changing race is in the Command Center, but is a different option than reset - resetting will still clear your account!
• Revalued weapons and tools. Both weapons and tools now reset for 70% of their original purchase price. Like sabotaged tools, sabotaged weapons are now immediately removed from the armory.
• Increased casualties suffered by powerful accounts attacking weak accounts. Also increased casualty rate of covert troops.
• Changed click trickle up to direct commander only - you will still receive a bonus when your officers recruit, but will not benefit if THEIR officers recruit
• Siege and fortification levels now increment by a percentage over their current multiplier, rather than incrementing by 25% or 33% over the base multiplier. This means higher level upgrades are much more important!
• Conscription (unit production) is cheaper and can be upgraded higher
• Increased maximum recons on a given target per day

Other changes:

• Now show morale of your officers on command center
• Added option to send PMs to all direct officers without counting against your hourly message limit
• Show rank and other stats on alliance pages
• Streamlined recruit page for faster clicking
• And of course, race bonuses have been changed
