One game, connected stores

Each store keeps its own prices and observations. We prefer the latest recorded EUR price for Europa. When the displayed currency differs from the store amount, a separate approximate value may use the latest available ECB reference rate.

Some store links may be affiliate links. We may earn a commission from qualifying purchases, at no extra cost to you. This does not affect prices, ratings or rankings. How commercial links work.

How this comparison works

Only original EUR amounts recorded for SE and matching titles linked to this game are compared. Edition words and numbers must match. Other editions, source-market fallbacks and currency estimates are excluded.

These are recorded observations. Check the store for the current price, availability and included content. Historical lows belong to the named listing in this market and reflect the history Lumiri GameDB has collected.
