The game runs on a tick-based system where the game state refreshes every 600 milliseconds. The input mechanics are mainly point-and-click. The artisan skills include skills such as cooking, crafting, and smithing. The gathering skills, such as mining, fishing, and woodcutting allow the player to gather in game resources. Combat skills aid the player in defeating enemy monsters or other players, with skills such as strength, range, and magic, among others. There is a large selection of skills, grouped mainly between three different categories: combat, gathering, and artisan. Users can gain experience points (exp.) and level up individual skills, making their playable character more powerful or more capable of using that skill. The player controls a single (human) character and can interact with NPCs, objects, and entities in the game world by left-clicking, or selecting an option from the object's right-click menu, since many objects can offer more than one interaction option. The basic mechanics are largely the same as RuneScape on 10 August 2007. It features a persistent world in which players can interact with each other and the environment. Old School RuneScape is an MMORPG with adventure elements. In-game screenshot, showing a player in combat with a goblin
