Hello, I'm an ex-LucasArts fan. A 'mojoer' if anyone comes from there is here. Loom is the best game ever. Straight five on any site. Anyway. You can upgrade your copy of Loom from the Underdogs website. Adding speech is optional. The speech pack is 49.7mbs It'll say you need to burn it to a CD, but just run it through ScummVM and it works. Link:
