A technology gets pricier as the empire grows, even when it is half researched

In many empire games every new city makes research dearer. If the saved progress is a point count, conquering one town can either wipe out half the work or hand out a free technology. This entry shows what to store so growth never cheats the player or punishes them for work already done.

Why this works

Progress means how far along something is, not how much was put in, because the price can move. Keeping the share done, rather than the points spent, means a rise or fall in cost never makes the bar jump, and half-done always stays half-done.

When not to use it

Skip it when prices never change during play, which makes plain points simpler and exact. Also skip it when you want a price rise to bite, so that work already done becomes worth less; then store points and say that openly.
