Ship Ahoy
A game set in the past where naval battle with the old ships and cannons were an everyday thing. This game idea may not be new or original. But there has not been any game that focuses on just ship battle. There are tons of games which has ship battle as a side mode but never as the main aspect. In essence this game would focus on all the elements of ships battle and making it stand out compared to other games.
This game would heavily rely on the physics that current technologies can provide. Seeing the waves splash, strong gales, ship debris when damaged. Those physics will be similar but more detailed like the destruction system you would normally see in the Battlefield series. The game could have 2 or 3 sides fighting against each other with 2 or 3 more ships depending on the number of players currently in the server. Of course during gameplay there are the cannoneers, musketeers, raiders and ship captain. Everything is split informally and everyone has the ability to fix up the ships to make the game more exciting and putting on pressure. Uniquely the raiders would be able to use ropes that hangs from the sailing trying to invade the opponent's ship. This action isn't auto and switch the player to a cut-scene but the player themselves will need to control where they need to swing.
In the end the beauty of this game isn't just the gameplay but also the aesthetic graphics that brings out the disaster and reckoning of a ship battle.
