Description
Enables access to all map tiles (529 by default, which is 88 extra tiles over the default game maximum; title counts may vary on custom maps).
This mod offers a choice of one of four methods to access these tiles:
Unlock all tiles: automatically and immediately unlocks all tiles on the map when you start a new city (or load an existing one). Quite straightforward.
Provide extra tiles at start: adds immediately-available tile unlocks when you first start a new city (all milestones will add their usual amount of tile unlocks on top of this); this enables flexibility with your initial start.
Provide extra tiles at final milestone: allocates the additional tile unlocks to the final game milestone. All earlier milestones are unchanged.
Allocate extra tiles to milestones: allocates an additional 88 tile unlocks across all regular game milestones, in proportion to the normal amount for each milestone, with any remainder (for maps with more than 529 tiles) being allocated to the final milestone. This enables steady unlocking over the course of a normal game.
There are also two options for locking tiles (these are only available if if 'Unlock all tiles' is not selected):
Optional custom selection of starting tiles, which enables you to choose your own nine starting tiles (at no cost) when starting a new map.
Optional re-locking of all currently unlocked tiles, if you want to change your mind about which tiles you purchased. Note that this will lock all map tiles and you will need to chose which tiles to unlock. This option is not available if 'Unlock all tiles' is selected, because (quite obviously) they conflict.
You can also change tile upkeep costs, increasing or decreasing tile upkeep (including reducing the upkeep cost to zero).
Instructions
Install the mod, load to the main menu, and go to 'Settings'. There will be a mod setting entry there for '529 Tiles' where you can choose the unlock mode (see above) that you want.
Changed in version 1.3: by popular demand, the mod will now leave the game unchanged by default. You must specifically choose an unlock mode if you want additional tile unlocks.
The selected unlock mode will be automatically applied to any new game started or existing save loaded. 'Unlock all' and 'Provide extra tiles at start' effects are instant; there is no need to unlock the first milestone to trigger any actions.
When purchasing tiles, the price of the final map tiles after the 441st will be locked (so the price won't keep on increasing for each tile beyond the vanilla game maximum).
Choosing your own starting tiles
The option to choose your own starting tiles is only available if 'unlock all tiles' is not selected, because (obviously) these two settings inherently conflict with each other; if you want to choose your own starting tiles you'll need to choose a different unlocking option.
When this option is any city you load will have all its tiles (re)-locked, so you can choose which ones to unlock again and leave the rest locked (if using this option the first nine tile unlocks are free).
Re-locking tiles
The option to re-lock tiles is only available if 'unlock all tiles' is not selected, because (obviously) these two settings inherently conflict with each other; if you want to re-lock tiles you'll need to choose a different unlocking option.
When this option is selected any new maps will start with zero existing unlocked tiles, so you can choose and unlock your own starting tiles normally (if using this option the first nine tile unlocks are free).
Tile upkeep
Tile upkeep costs can be changed using the multiplier slider, ranging from 0% (disable upkeep entirely) to 200% (double the upkeep costs compared to the base game).
Meta
Safe to remove at any time
This mod is not required to load any saves made with it. Saves made with this mod will work fine without it (any unlocked tiles will remain unlocked, even if you don't have this mod).
