Star Wars: Knights of the Old Republic: 3 Open Source Clones Compared
xoreos aims to cover several BioWare Aurora-engine games at once (Neverwinter Nights, both KotOR games, Jade Empire, Dragon Age), but its own known limitations state that no actual normal gameplay is implemented yet — only partial graphics, menus, and a rudimentary script system. KotOR.js focuses on KotOR specifically and, while still in early development, already has many engine systems working in some form, plus an early in-progress modding tool called KotOR Forge. reone has no published details here to compare.
