This is better than 25th Anniversary with more complex missions and three difficulty options for the space combat (along with the new ability to lock your weapons on target - just like in the TV show). The problem I have with this is the CD-ROM version, or at least the Linux version I played (haven't tried the Windows port). I have the original floppy version of Judgement Rites, with the bonus "Movie and Sound Pack" (for a whopping total of 15 3.5" floppy discs!). I figured I would try out the CD-ROM version here and I was... slightly disappointed. In addition to the original series actors sounding expectedly too old to be playing their 1960s selves (except William Campbell as Trelane - the guy sounded like he didn't age a day over 30 years and gave a great performance!) and William Shatner sounding bored with everything I think when they crammed all the voice work on the 700mb CD they must have taken a lot of stuff out too... the opening movie is gone now and I swear some of the music is changed around/taken out in spots. If you already own the original floppy version of this like I do you can probably pass on this. The idea of having the game voiced by the original actors is neat (this was the last thing DeForest Kelley worked on before he died - RIP) but the execution isn't all that great and to me isn't worth it to lose some of the stuff from the original version. If you have never played Judgement Rites though go ahead and get this.
