I have never found full guide which would meet my ideas, so i'm posting it here to save someone about 3 days of searching and modding. Ideas (check if yours are same): - Huge & Marathon maps with lots of cities - Civ1 style - Less focus on units&"damn another civilization" mods, more on interesting, global, historic gameplay Guide: Part 1) Game general optimisation - Game and mods dds files can be compressed with dds tool, with insane compression ratio 1000MB -> 200MB sure this works on terrain folder in game dir, unsure if it will work on other dds must have, gives good speed of map Music files usually can be compressed too, about 3GB -> 2GB. Requres some additional skills with Total Commander and any batch music tool-Quick turns mod included here-Notice to check with RAMMap program if your PC gets nonpaged memory leak. Means restart PC after every Civ5 executionPart 2) Adding mods Done by full search of CivFanatics, Steam Workshop, Google and removing conflicting mods Some mods are changed for compatibility & speed (mostly it's duplicate lua&xml checks) UI - Unit List Enhancements (v 11)\ UI - Notification Options (v 13)\ UI - No Auto-Embark Workers (v 7)\ UI - Condensed Promotions (v 15)\ Trading Posts Grow into Towns (v 6)\ Titans of Commerce Science and Industry (BNW) (v 5)\ Smart AI (v 3)\ Artificial Unintelligence Lite (v 9)\ reform and rule (bnw) (v 25)\ Quick Turns (v 10)\ Promotions - Expansion Pack (v 9)\ one-color civs (v 2)\ LightTouch (v 6)\ (option to fortify units must be removed on start of game and enabled later) Less Warmonger\ Historical Religions Edit (BNW or GK) (v 45)\ Greatest Cities (v 11)\ JFDs Cultural Diversity (Soundtrack) (v 1)\ (one of these music mods) Faerun Soundtrack (v 4)\ CooperBuff\ 9 RED. Modpack (v 28 beta 2b)\ 9 r_e_d__xtreme__v_27\ 9 CivWillard for BNW (v 2)\ 3_Emigration (v 6)\ 2_2 Zwei833's Renaissance Era Revised (v 2)\ 2_1 Enlightenment Era (v 5)\ 1 JFD's Cultural Diversity (Core) (v 7)\ 9 CivFixes\ (my own fixes, with noticable effect and litte size) Additional for future Era Reforestation (v 8)\ PFfaster_aircraft_animations__v_3\ 3 Industrial Building Pack\ 2_3 Future Worlds (v 4)\ Notable, but not tested or not used, or optional yet__not__another_earth_maps_pack__v_22\ - Crusader Kings Mod and Scenario (forgot to include in archive): Extremely good map and civ screens, other content not working with mods above Quiet Diplomacy (v 7)\ (can be easily replaced with manual string in two game lua files, saving space for new dll mods) 9 IGE\ Bugged, but very cool cultural_diffusion__v_18\ (v18 makes huge slowdons on late game phases on huge maps) Global Warming (v 7)\ (makes lots of resources instead of removing them) Community patch mods. They never ever worked on huge and marathon maps, due to horrible bugs, slowdowns, and crashes. Lots of other mods, rarely tested on huge and populated maps CivFixes are my own ideas and fixes, pair of them are really useful -no more diplomatic spam, no more open border annoy - all fixed with just two or three strings in lua. ! Could be helpful for other modders ! diplo screen instantly closes on these cases -no cheat promotions like two attack per turn or heal, no experience from ranged attack on units, no heal on enemy territory, slower heal in general (it's war after all, sometimes you must spare soldiers) makes game harder, more real, more interesting, medic is better now -better natural wonders yields, road gives +1 gold, railroad +1 production now roads became more interesting, since you need to build them on useful places no more railroad spam since it's costly of course these must be combined with proper maintain costs, and seems it works fine with bnw setting -modified marathon for very slow research speed and fast production, of course. look for VER_General.xml for any taste -slower city growth, 3 food required per citizen, faster culture spread for CultureDiffusion gives Civ1 feeling, previous idea was to make resource yields better and desert & ice cites useless (again, more real, less stupid balance) now i removed all yields and replaced with just 3 food per citizen for compatibility -no more than 3 wonders per city much better mod here is Native Wonders, but it's bugged for BNW -fixed unit maintenance which depends on their cost and strength formula in sql file seems (= C/10 + S/10) much better than inflations, but seems buggy and undocumented probably can be improved with other mod Part 4) TODO -Lua dll tests -Inflation is replaced with cost formula now, but not visible for every unit -full log sql&other clean-up (for now, fixed only some lua errors) -improved unit maintain ideas\mods\sql formula, not sure if this works Archives: Mods: https://yadi.sk/d/owQ4d8sarhMyB (List i used for crusader kings scenario game, but without conflicting scenario xml etc files) ! Soundtrack mod is not included, since it's about 3 GB ! Other mods: https://yadi.sk/d/7GOeKzcNrhNBJ (Some of them work well with pack above, like era mods, tested on quick and small map full eras gameplay) Tools, lua dll variants: attachment Since links on yadi.sk are very fair (good hosting. no ad), I feel like this little violation is allowable. Terribly great thanks for all mod authors! It's just no one have 3 spare days to check compatibility, to fix issues, to do tests etc. There must be better system, but now it's all manual and very very slow .
