NWN2 - Runescape Mod

@PC Gamer A group of modders has spent six years rebuilding Runescape in NWN2.

"I really enjoyed playing private servers on Neverwinter Nights," Aaron explains. "I also loved building my own maps-it was never anything serious, I was just a kid at the time. But at one point, it came into my head that I should rebuild an area of Runescape in Neverwinter Nights." Aaron showed his clan in Runescape his creation, and their positive response spurred him to keep building more and more areas for them to play around in. Six years later and that little hobby has turned into Molior RS, an ambitious recreation of Runescape built by Aaron and a team of four amateur modders.

Runescape's skill system is probably where Molior RS wrestles with Neverwinter Nights 2 the most, as the games feature drastically different mechanics and character progression. In Neverwinter Nights 2, which uses Dungeons and Dragons 3.5 edition rules, your character is the product of abilities like strength, wisdom, and dexterity, which further impact various skills, spells, and special feats. Runescape, however, features a much simpler system without class restrictions where players can level up every skill independently just by partaking in specific activities. Right now, Molior RS is on its fourth rendition of the skill system. It's been a massive undertaking only made possible thanks to Triston Barker, the lead programmer for Molior RS, and his ability to dive deeper into the Neverwinter Nights 2 toolkit and reprogram it from the inside out.
