How to Create a Roguelike Game
Why Roguelikes Are Indie Gold
The roguelike genre has produced some of the most successful indie games ever:
- Hades: Game of the Year, 5M+ sales
- Slay the Spire: Defined deckbuilder-roguelike hybrid
- Vampire Survivors: $1 game, $50M+ revenue
- Risk of Rain 2: Multiplayer roguelike success
The Core Loop
ROGUELIKE CORE LOOP
====================
START RUN → Choose starting loadout
↓
ENTER ROOM → Random encounter (combat/event/shop/treasure)
↓
CLEAR ROOM → Get reward (item/upgrade/currency)
↓
CHOOSE PATH → Player picks next room (risk vs reward)
↓
BOSS FIGHT → End-of-floor challenge
↓
NEXT FLOOR → Harder enemies, better rewards
↓
DEATH → Lose run progress
↓
META PROGRESSION → Spend permanent currency
↓
START NEW RUN → Slightly stronger, new knowledge
Procedural Generation
Simple room-based dungeon generator
import random
class DungeonGenerator:
def __init__(self, floors=5, rooms_per_floor=4):
self.floors = floors
self.rooms_per_floor = rooms_per_floor
def generate_floor(self, floor_num):
room_types = ['combat', 'combat', 'combat',
'elite', 'shop', 'treasure', 'event']
Harder floors have more elites
if floor_num > 3:
room_types.extend(['elite', 'elite'])
rooms = []
for i in range(self.rooms_per_floor):
room = {
'type': random.choice(room_types),
'difficulty': floor_num * 1.5 + random.random(),
'connections': []
}
rooms.append(room)
Boss room at end
rooms.append({'type': 'boss', 'difficulty': floor_num * 3})
return rooms
