Men, this MOP is almost a kingsbounty+heroes cocktail :). Mapgen work perfectly, with templates.
I cant believe, i never heard about this mod, only now discover in the darkest holes of web.
-artifacts (143 new)
-creatures (40 new neutral, some new regular, reskin almost all)
-spells (some new adventure and combat spells, rebalanced magic system)
-skills (one new, many others extended and balanced, remove skill limit, new page for skills on hero screen)
-objects (new and reskinned buildings and other objects with new functions, wandering teachers, raid bosses)
-town relics (dozens of differents with various bonuses, work as grail)
-towns (some changes, and can build new towns on empty places)
-interface (new and extended screens and dialogs, buttons for new and old functions, hotkeys, additional informations)
-marriage (between two hero, grant various bonuses - as kings bounty)
-heroes (totally reworked with new names, specialists, portraits and full images)
-WoG features balanced and extended (as spellbanning with images and categories)
-templates for random map generator (as hd mod)
-other (as artifact bag, treasure digging, creature-specialists can recruit from far the favorized creature, and so many else)
Interesting and useful informations:
-extra tools (as creature editor)
-made in russia, but fully english in-game, no language problems
-illustrated documentation (unfortunately this is russian)
-source code is available (assembly language with russian comments, but of course, erm is work)
-random templates work perfectly, but no combobox for chose (need copy only one to data folder and keep “rmg” name, or copy all with different names and type name in game)
-own installer (but you can extract anywhere and copy later too)
-separated files, no owerwrite anything (only the mapeditor not compatible with the original)
-own mapeditor (open old maps, set specification-version-wog, save to mopmaps-folder and perfectly work)
-some popular new wog objects not included, but you can add files to mop with mmarchiver, so any non-scripted map work (im not tested with scripted maps)
-the only one missing: high resolution.
-the versions is names: 1.0=seek & destroy, 2.0=ride the lightning (creators metallica fans sure :D)
-project is closed in 2013, rtl is the final version (some russian fans try with an expansion, named as “battery” - hehe, but they will fail)
I play homm3 long ago with hd and mods (hota, lord, and dozens of smaller), but this is better alone.
Summary: ubisoft go to hell with ros hd edition and homm66
