+# Instructions Clear
+
+Instructions Clear is a Multiplayer Online Battle Arena (MOBA) where two teams of five players fight for victory.
+The players have the ability to upgrade their abilities via their gear earned from quests.
+But make sure to prioritize resurrecting your allies first because once you wipe, it's all over.
+The game blends some elements of traditional MMORPG dungeons with modern MOBAs.
+
+## Design Pillars
+
+| Power | Reaction | Competition |
+| --- | --- | --- |
+| Players gradually get stronger as they complete quests. | Quests provide upgrade paths that provide opportunity to adapt. | If not by sheer power or a good build, teams have to outperform the opposing team to win by any means. |
+
+## Audience & Market
+
+The game is designed to be played online.
+Elements of the no longer popular MMORPG genre are used to give former players a modern game.
+It is aimed at young adults.
+
+## Core Gameplay
+
+The game controls are single unit isometric Real-Time Strategy (RTS) style (point-and-click).
+
+The player can decide the pathing destination via right mouse clicks, combine it with auto-attacking the closest target via left mouse clicks, and cast abilities using the Q, W, and E keys.
+
+Players of the same team collectively deal damage to players of the other team to bring the members' health points to zero. If a team's collective health pool has run out, that team loses.
+
+Quests provide the income of players. Each quest gives the option of changing an ability or cashing out for gold.
+
+Abilities provided by quests can either be a "legendary" (main) ability or a "basic" (minor) ability. A player is limited to one legendary ability per game.
+
+The main ideology behind legendary abilities is the traditional damage, control, support trio.
+
+Gold can be used to resurrect others (in lieu of a specialized ability), and to upgrade ability slots (to scale power).
+
+The game is likely to provide a single level only.
+
+## Mechanics for mechanics
+
+The game concept is mainly dictated by MOBAs with the tried and tested systems, however, there are differences:
+
+* Abilities replace items to reduce the possible combinations and to ease the learning curve.
+* Quests replace last-hitting to make income more diverse to enable traditionally low-income roles like position 5 supports to earn equally.
+* The win condition is changed to team elimination instead of the destruction of the main structure so that the game is more centered around the already celebrated team fights.
+* Equal, generic ability kits replace heroes (or champions) to eliminate the possibility of a "lost draft" at the hero selection phase.
+
+TBD: What are quests?
+TBD: How (and if) structures work
+TBD: Unlike in the Defense Of The Ancients (DOTA), the core structure (the Ancient) is not a win condition but it provides a safe haven until destroyed.
+
+## Gameplay Balance & Pacing
+
+As all MOBAs, if balancing is not perfect, players will gravitate towards "metas" to win.
+
+TBD: The pacing is so that it doesn't feel like too much preparation but it isn't dragged out.
+TBD: The "AFK farming" tactic should be crossed out by giving players incentive to fight.
+
+### Possible Issues
+
+**Corpse camping:** After a successful pick, the enemies would not let the picked player revive.
+
+**Long death timers:** The player can get bored until they get revived.
+
+## Setting & World
+
+TBD: Diagonal lanes or a free-for-all layout?
+
+## Narrative
+
+TBD: Gameplay is king, narrative is going to be an afterthought.
+
+## Business Model
+
+This is a free-to-play game. Since running servers costs money and the server binary is not public, a subscription model can be introduced to spin up more servers on demand instead of waiting in queue for the free servers.
+
+The cosmetic aspect ("skins" on the player model) is supposed to be responsible for the majority of the income.
+
+## Timeline
+
+1. Prototype with working pathing
+1. Win condition: full team elimination
+1. Basic ability mechanics
+1. Ability upgrades (upgrade trees)
+1. Quest mechanics
+1. Quest type diversification
+1. Retrospective to plan the remainder of the timeline
