Exception: Some stores (e.g., Steam) may sell the Special Edition as a “bundle” that discounts if you already own Standard – but not guaranteed. Get the Special Edition – even at full price. The extra campaigns and castles add real replay value, and the lack of an upgrade path makes it cheaper long-term. If you’re on a strict budget, wait for a sale; the Special Edition frequently drops to ~$15–20, which is excellent value.
