Freely excavation of archaeological sites

TL;DR: Excavate any site. AI plays by vanilla rules. Want your science ships to excavate archaeological sites the moment they are discovered in deep space? Eager to snatch those lucrative relics from right under an AI empire's nose? This mod grants you the freedom to excavate any archaeological site​ your ships can reach, breaking the restriction of national borders. ◆ Core Feature & Mechanics Excavate Any Idle Site:​ You can now begin excavation on any archaeological site that is incomplete and idle, regardless of whose borders it's in (including AI empires), as long as your science ship has access. Respects Activity & Completion:​ You cannot start excavating a site that is already being worked on or is already completed. The site must be unfinished and not currently occupied​ by another empire's science ship. Claim via Conquest:​ If a site you desire is being excavated by another empire, you can declare war to destroy or drive away their science ship. Once the site is cleared and becomes idle, you may claim it for yourself. Pure Player Advantage:​ The AI continues to operate by vanilla rules, only excavating within its own borders. This mod does not allow the AI to excavate in your territory or elsewhere.​ The freedom is yours alone. ◆ How It Works & Technical Details Rule Change:​ This mod works by modifying a single rule​ in the game's game_rule​ definitions related to archaeological site access. Simple & Lightweight:​ Only one rule is changed, making it a very lightweight modification. Compatibility:​ It should be highly compatible​ with other mods, as very few target this specific rule. If the mod does not work, it is likely because another mod has overwritten the same rule. ◆ Development Status This mod is considered complete and stable. It is expected to work permanently unless a future game update fundamentally changes how archaeological site access is governed in the game_rulefiles.
