Loom has been released several times, but there is no clear-cut “best version”.
In the original DOS release, Expert mode rewarded players with an additional scene toward the end of the game. It is not present in either of the above versions.
Finally, while both options offer repainted 256-colour graphics (an upgrade from the 16-colour originals), those in the FM-TOWNS version are underdeveloped in some locations when compared to the CD release.
If you think you would prefer the FM-TOWNS release, you can download it from this site once you have proven that you own Loom on Steam. This involves entering some characters from a Steam-only script file that comes with the game and has nothing at all to do with your Steam account!
