What is Battle Mechanica?
Battle Mechanica is an attempt at creating a tabletop wargame that forgoes the use of dice-rolling to determine an outcome. It instead uses diceless combat resolution that uses simple calculations to make the game easier and faster to play, while remaining tactically realistic and engaging.
This game was inspired by a lot of gaming systems. Its core mechanics was primarily inspired by Little Fantasy Wars and Hordes & Heroes, while the units took inspirations from Games Workshop's Warhammer: 40,000 universe. It uses paper cutouts as units and terrains, but players may use miniatures and 3D gaming terrains instead as long as they in proper scale.
Why use a diceless system?
Dice-rolling systems rely on chance to resolve an outcome, where your success is entirely dependant on having as much dice in your hand as possible. It also tends to lead players into taking extreme risk by hoping for a miracle roll - which is antithetical to a sound, tactical approach. In actual warfare, generals do not take chances; though commanders do at times take calculated risk, they do so only after meticulous planning.
By taking out artificial randomizers (such as dice) from a wargame, players will have to execute brilliant tactics rather than counting on blind luck to win a battle. Just like in a poker game, a diceless wargame is where you play against your opponent's skill, not your opponent's luck.
The diceless combat system - In a nutshell
The system uses simple attribute comparison to determine whether a unit could cause casualties upon the ranks of the enemy. In melee combat, for instance, two opposing units simply compare their Combat attribute against one another - the unit with a higher Combat attribute therefore will cause casualties on the other unit, while the other unit will most likely only be able to weaken it's enemy (that is, injuring or wounding the enemy ranks).
This simple system is used in many aspects of the game, from determining whether a charge could break the ranks of an enemy infantry to calculating whether a unit of spearmen could falter after the third wave of attack.
