Generic Chess Piece Creation System
This is a system for construction of pieces, with some roots in Buypoint Chess and A Chess-like Variant Construction Set. This one, however, is intended to be much more freeform, bringing ideas from RPG games.
Base PieceThe base piece costs 10 points for each square it occupies. A piece like this can't move, capture or do anything deserving of respect: It just stays there and can be captured. You'll probably want to buy some Moves for the piece.
MovesSecond, you can buy Moves, which define the mobility of the piece. Each Move has its base cost that is added to the value of the piece. A Move can be boosted beyond its basic status via Advantages and Limitations, which will alter its cost. First, to the Move cost:
Move type Cost Description Orthogonal 3 Moves one square in a single orthogonal direction Diagonal 2 Moves one square in a single diagonal direction Leap 2 Combination of orthogonal and diagonal moves (1/8 of a Knight move) Composite X Sequence of moves in a row, bought as a single move Extra X Extra moves (see in special box)Leap Moves: A combination of orthogonal and diagonal moves. 2 points each. A combination of 8 leap moves (reflections and rotations), like a Knight move, costs 16 points. Composite Moves: A sequence of moves the piece does (Like the Crooked Bishop, that does two Diagonal moves in a row). Add the move points of all the moves in the sequence. The piece can stop anywhere in the composite move. Each part of the composite move can have its own advantages and limitations! Extra Moves: Things that didn't fit here. See below.
Advantages and LimitationsEach move or group of moves can be stretched with the use of these, altering its base cost: For example, a group of the 4 Orthogonal moves can be bought with Repeat Infinite, turning it into the basic Rook move.
Repeat N *N Can repeat the move N times Repeat Infinite *5 Can repeat the move indefinitely Leap *2 A leap move can leap over other pieces Leapwalk *4 The piece can repeat its move over other pieces Dual Move *4 Can move twice Dual Strike Move *8 Can move twice, capturing on both moves Tri Move *16 Can move three times Tri Strike Move *32 Can move three times, capturing on all moves Pusher *X Pushes (x-1) enemies on the line Momentum *2 Keeps repeating move while possible Leap Capture *2 Leap move captures piece it leaps over, stops (unless Unstoppable) Approach Capture *2 Attacks enemy piece by approaching Sandwich Capture *2 Attacks enemy piece with another friendly piece after it Retreat Capture *3/2 Attacks enemy piece by retreating Rifle Capture *3 Can capture an enemy piece without moving Doesn't Capture /2 Can't capture in that direction Doesn't Move /2 Can't move without capturing in that direction Unstoppable *3 Can capture a piece without ending its turn Single Chance Move /4 A move that can only be taken once in the game Must Leap & Stop /2 Must leap over a piece, lands on the square after it Only Threatened /2 Only Not Threatened /2 Kamikaze /4 Kamikaze Move: Piece is sacrificed after its endSome pieces not only move, but have special abilities: They attract other pieces, repel them, destroy them... Those pieces have Powers.
PowersPowers are special abilities of pieces. The powers can be Passive or Active. Active powers only work when the piece moves or captures. Passive powers act at the end of every turn. The power base cost is just as a move base cost, representing the squares the power can affect. Apply the modifiers below for the specific type of power:
Attraction *1 Attracts friendly OR enemy pieces Repulsion *2 Repels friendly OR enemy pieces Magnetism /2 Repels friendly pieces, attracts enemy pieces AntiMagnetism *1 Repels enemy pieces, attracts friendly pieces Conversion *2 Changes friendly OR enemy piece's allegiance Poison *2 Poisons friendly OR enemy pieces Movement Gift *(1/10) Grants extra movement to friendly OR enemy pieces - cost is 1/10 of the move Power Gift *(power)Grants extra powers to friendly OR enemy pieces - cost equals power cost Immobilization *2 Immobilizes friendly OR enemy pieces Burn *3 Destroys friendly OR enemy pieces
ModifiersThese affect the nature of the power.
Passive Power *2 Power is always activated Chaos Power /2 Skills are granted to all pieces, not just friendly OR enemy onesExample: The Fiery Dragon has the Passive King Burn. King move is 20 points. Burn is *3, and Passive is *2. The total score is 20*3*2=120. Plus the Bishop movement of the Dragon gives a grand total of 170.
Extra MovesMoves that change with time: 'Special' moves. Can be bought more than once, and can be bought with the move advantages and limitations.
Mimic 50 Mimics any pieces (protecting/attacking) it Imitator 50 Imitates a certain piece - Last (any/friendly/enemy) moved piece - Last (any/friendly/enemy) captured piece Assimilate 30 Mimics last piece it captured Metamorph 30 or average of all move types, whichever's larger Move depending on column/row piece is in
Piece ModifiersAfter buying all moves and stuff, you can apply these modifiers to the final cost:
Colorbound Piece -5 Can only walk on one color of the board (Diag) 1/4 Bound Piece -10 Can only walk on 1/4 of the board (Orth2, Diag2) Can't Capture -10 Can't capture, ever Can't Be Captured *5 Can't be captured, ever Promotes +5 Promotes Reproduces *3 Can reproduce Spins *2 Can spin in place, changing direction marks Spawner +(point cost*2) Spawns other pieces Royal *5 Losing all loses the game Checkmate *2 Can only be captured by checkmate Poisoned *3 Piece that captures this piece is also captured
