So at a high level you game looks like this 

Main
	gameEngine = GameEngine()
	renderEngine = RenderEngine()
	baseSurface = Display.get_surface;
	
	while 1
		pygame.FpsLockThingIforgetTheName(60)
		gameEngine.Step()
		renderEngine.Render(baseSurface, gameEngine) 
	

GameEngine contains top level game objects so it may look like

GameEngine
	Character
		HP
		Pos

	ItemList
		Name
		Damage
		Owner
		Pos

	SpellList
		Name
		Damage
		CooldownCost
		CooldownLeft
		Caster
		Target

	EnemyList
		HP
		Pos

	Map
		Name
		TileList
			Passable
			Pos

	Step()
		SpellBehavior()
		EnemyBehavior()
		CharacterBehavior()

		
Then you have your RenderEngine object which examines the GameEngine object and renders the current state of the game. It gets hard
because pygame makes it seem like you need to bind a particular sprite to a particular game object. But this isn't true, you can make
pools of each different type of sprite and just use any sprite from the pool to render a game object. This is actually more efficient
too because rather then newing up a sprite for each bullet you fire you just reuse the same ones from the pool. It may look like



RenderEngine
	CharacterSprite
	EnemySpritePool
	FireballSpellSpritePool
	SwordSpritePool
	MapTileSpritePool

	CurrentMap


	SpriteLayer
	UILayer
	MapLayer

	Render(baseSurface, gamestate)
		if(gamestate.Map.Name != CurrentMap)
			MapLayer = renderMap(gamestate.Map)
			CurrentMap = gamestate.Map.Name

		UILayer = renderUI(gamestate)
		SpriteLayer = renderSprites(gamestate)

		blitLayers(baseSurface, SpriteLayer, UILayer, MapLayer)
