If you can run NWN2, you should be able to run the NWN2IS. In terms of system requirements, they are the same as the requirements for Neverwinter Nights 2. Battles take place in real time the combat system offers an active pause feature that lets us stop the game and calmly issue orders. While playing, we explore locations, develop our character, perform quests, and fight.
However, theoretically, it should work with any version of Neverwinter Nights 2 updated to the latest version. Neverwinter Nights: Enhanced Edition is a classic PC RPG. NWN2IS was developed and tested with the English version of Neverwinter Nights 2 Platinum (which includes the Mask of the Betrayer and Storm of Zehir expansions). Customization by way of table editing is also available for those who would rather not do scripting. If the available criteria are not enough, with a little scripting knowledge, it is possible to add additional criteria. Each character is given their own personal settings.
Through an in-game interface, players are given a choice of which criteria they would like to use to sort each of their characters' inventories. It also features the ability to sort containers in the inventory such as magic bags. The NWN2 Inventory Sorter (NWN2IS) is an engine that attempts to address this issue by allowing players more control over sort ordering. As it stands, the sort ordering is predefined and although it offers ordering with some frequently used items occurring first, it is not suitable for all players. Neverwinter Nights 2 is a great game with many interesting features, but one thing it lacks is control over inventory sorting.
