game_test is likely a technological demo for the engine, written by brick-luke.

Ditto, except it was probably meant to be for car object testing.

game_run is about running from zombies while you have 5 lives.

game_classic is likely a technological demo, too.

game_luke, also known as Luke's Game is about running over random people with your car.

• No multiplayer
• 2D release can be started via game_test only, because it's the only folder in game's release, though incompatible 3D release games can be played fine with this client.
• 3D release can be started via game_luke only, because other games don't have the draw.txt file to be executed by the game's code.

• W,A,S,D - Up, down, left, right.
• Shfit - Crawl (3D Release exclusive).
• Space - Exit the car.

- game folder (eg: game_nut):
-- system_map (3d exclusive directory)
--- draw.txt
-
-- system_player
--- function.txt (can be empty)
--- player.png
-
- background_nut.png (defined in settings.txt file)
- gamemode.txt (creation event?)
- gui.txt (what to draw)
- settings.txt (game settings)

Script examples:

gamemode.txt:

while vehicle != 1
	{
	instance_create(room_get_width/2,room_get_height/2,system_vehicle)
	vehicle += 1
	}

gui.txt:

if (global.player_lives > 0)
	{
	draw_text(2,2,global.player_lives)
	}

settings.txt:

//Control Game Settings Here
global.player_walkspeed = 4
global.player_spawnpoint_x = room_width/2+random_range(-100,100)
global.player_spawnpoint_y = room_height/2+random_range(-100,100)
global.player_lives = 5
global.background = "background_race.png"
global.ai = ""
global.vehicle = "racecar"

It seems like that the codebase of 3D Role Block release was the main codebase until the first full rewrite by brick-luke in 2017, because of how differently 3D initialization works. In Early 2017 Brick Hill workshop, the game's code creates obj_environment for environment initialization while also initializing GMNewton for physics capabilites. While the 3D Release of Role Block does it via system_player object.

Though the 3D Release requires the draw.txt file to create a system_brick object, it may be misinterpreted as a floor drawing procedure.
