Anyone who owns Stephen Coombs' Early Scriabin album knows that Scriabin wrote down a second, more harmonically interesting and extended version of Op.8 No.12.
For me, the first version is just so potent that I cannot turn away from it, but the 2nd version is still very unusual, utilizing a lot of the harmonies that Scriabin would later use in the Piano Concerto. It sounds a lot less "Chopinesque" (not that the 1st version is all that similar to Chopin, but you get what I mean, right?)
Discuss.
