Stadium

First the game estimates how many people want a ticket. The home club matters most because it owns the stadium and supplies most of the crowd. The visitor also matters — an entertaining opponent can make the fixture more attractive — but its Fun Factor carries only 40% of the home club’s weight. This difference changes attendance only; it gives neither team an advantage on the pitch.

For the exact calculation, the home Fun Factor multiplier is 0.50 + FF ÷ 100 and the visitor’s is 0.80 + FF ÷ 250. Popularity, league position, recent form, the opponent’s place in the table, promotion or relegation stakes and a seeded ±6% matchday variation also affect demand.

The Fun Factor used here is the standing value from before kickoff. Today’s played plan changes that rating after the gate has been stored, so it affects later demand rather than the crowd already present.

Seat classes are created automatically in a fixed mix and fill proportionally. VIP, luxury, seats and stands have different yields, exposed on the stadium page as a blended amount per spectator. Maintenance is already deducted; no later upkeep line appears.

• Ordinary league gates split 60% to the home club and 40% away.
• The first league round of a season splits 50/50.
• Only competitions listed in the matchday economy produce stored stadium receipts.

A quote uses the published per-seat rate plus one fixed anti-nibble fee based on today’s capacity. The exact expected cost and capacity are submitted again when construction starts; if either changed, the game returns a fresh quote instead of silently charging another figure.

• Minimum expansion: one seat. Maximum total capacity: 260,000.
• Build duration: five real calendar days.
• Existing capacity remains usable during the build.
• Only one expansion can be active, and the cost is charged immediately to the ledger.
