 # Ordoor

 Ordoor is an **unofficial** [game engine recreation](https://en.wikipedia.org/wiki/Game_engine_recreation)
-of the classic game from 1998, [Warhammer 40,000: Chaos Gate](https://en.wikipedia.org/wiki/Warhammer_40,000:_Chaos_Gate)
+of the Random Games, Inc., [Strategy Engine](https://www.mobygames.com/game-group/game-engine-random-games-1996-2000-strategy-engine),
+which was in use from 1996 - 2000.

-**You must have a copy of the original game data to use this project**. GOG is
-the current publisher of this game; [you can purchase it here](https://www.gog.com/game/warhammer_40000_chaos_gate).
+Four games are known to have been published for this engine:

-"Warhammer 40,000" is a trademark of Games Workshop, and the game data used by
-Ordoor contains Games Workshop intellectual property. I am confident that this
-project uses all those things in accordance with the
-[Intellectual Property Policy](https://www.games-workshop.com/en-GB/Intellectual-Property-Policy)
-and the license granted when purchasing a copy of the game in question. Do let
-me know if you see or suspect any violation, and I'll address it immediately.

+* [Avalon Hill's Squad Leader](https://en.wikipedia.org/wiki/Avalon_Hill%27s_Squad_Leader) (2000)
+
+The aim of Ordoor is to be a complete reimplementation that allows all four
+of these games to be played on modern hardware. It should also permit new games
+of the same style to be built.
+
+For each of the games above, **You must have a copy of the original game data to play**.

+your back catalogue, or perhaps a local charity shop.

+Trademarks and intellectual property are the property of their respective

+copyright. As a mere game engine recreation, we're confident that this project
+operates legally, and that its goal is a noble one. Do get in touch if you
+believe otherwise!

 seems to use the same engine. Maybe at some point Ordoor will be able to play
 both. Will that need a rename? Hmm. Watch this space.

+## Long-term goals
+
+Once full playthrough of the official single-player campaign for all four games
+has been achieved, thoughts turn to other things we could do. Here are some
+ideas, mostly at random.
+
+Multi-player support.
+
+Graphics enhancements - 3D models instead of sprites, high-resolution tile sets,
+32-bit colour, etc. Hopefully we'd be able to drop these in one at a time.
+
+Vastly improved AI.
+
+Mash-ups? How do mercenaries fare against cultists fare against Nazis? Only one
+way to find out!
+
+New campaigns with existing assets. Tell new stories, or elaborate on / modify
+existing ones.

-To build this palette, I did the following:
-
-* Created the .asn + .obj files by hand
-* Referenced them in a .set file and asked WH40K_TD.exe to render the sprites
-* Screenshotted the output and used GIMP to create a 1x255 image with them all
-* Exported that image as an ASCII .ppm file
-* Used the `generate_palette` script to output Go code \o/
-
-Note that palette index 0 is ignored, and hardcoded to be transparent black.
-This is because 0x00 seems to be used as a record separator in .obj files, so
-can't be used as a palette index anyway.
