Differences between G3 and G4

• A new map, with changes to the geography, skills and markets of the non-surface worlds (Hades, Faery, the Cloudlands and the Subworld)
• Slight changes to skill distribution in cities on the surface
• Changed the research requirements of a bunch of skills and renumbered them to make the skill descriptions tidy again. See the skills page for the details
• Made aura costs for gates and teleporting match what the skill descriptions say
• Added a starting option to start in a random non-safe-haven city that has no-one in it
• Increased returns from pillaging, but increased recovery time too
• Stopped garrisons without enough soldiers from doing garrisonny things
• Increased breed time of Centaurs to 14 days
• Re-enabled civ level restriction on research by powerful mages
• Made it possible to get scrolls teaching category skills from quests
• New players are automatically given a random password
• Made the game engine a bit more configurable. This allows changes to garrison pay (now 2gp/day), auto-quit (now turned on after 8 turns of inactivity) and number of men that reduce a noble's movement speed (now 20) to be made without changing the source code.
• Prevented castles from being destroyed by unsuccessful sieges
• Cleaned up FORGET handling
• Healing potions now restore health as well as curing sickness
• Added opium to swamps
• BUY and SELL orders with no price given are now rejected rather than assuming a price of 1
• The contact order is no longer silent
• Fixed a number of bugs, including:
  • "MAKE 52 0" not terminating properly
  • "COLLECT 31" not requiring any skill
  • Building with large numbers of workers not using all the required resources
  • Random monsters in Hades and Faery now respect Transcend Death and elfstones respectively
  • Noble ranks are now reduced when you pledge
  • Auraculums now require materials to create
  • UNLOAD no longer unloads members of the captains' stack
  • Bird Spy [651] now works if the user is inside a structure
• A bunch of (hopefully) invisible changes to make Olympia run on modern systems
