Several trial versions of "Tsukihime" were released before its full release. The first preview version of "Tsukihime" was released at Comiket 56 in 1999; only 300 copies were distributed for free on 3½ floppy disks. The game was so early in the making that the cast had not been finalized yet. At the next Comiket 57 in late 1999, a trial edition was released with only 50 copies being distributed on 3½ floppy disks. The cast was still not finalized at this point. At Comiket 58 in 2000, "Tsukihime Half Moon Edition" was released; 300 copies were sold for 1,000 yen each. This version contained Arcueid and Ciel's "Near Side of the Moon" storylines.
