I have played a character on TrekMUSH: Among the Stars for a significant period of time, and it is a moribund game. Its only life support is a group of players who connect out of habit and to no enjoyable purpose but socializing.

With one exception only, a friendly roleplay admin named Niner, the staff no longer cares. They are resting on 20 years' worth of dead laurels and visibly interact with the main player base only when they want to punish someone. Nerva only connects to demote Federation officers. Soggy only speaks up to threaten people or make snarky remarks. Attuare only becomes visible to permanently disconnect players from the game. The distinct impression one gets is that the admin are bored with the game but would rather see it languish or perish in its present state than allow anyone else to take over and fix it. They don't care; they're only there to remember the good old days.

As far as Star Trek, the game has traded Roddenberry's vision for a corrupt, belligerent Federation that's intent on fighting rather than exploration. Every player is given a ship, so there is almost never any crew community developed on a single vessel. One fights automated pirates or invades the Delta Quadrant to seek and attack Hirogen, Kazon, and Borg bots in between making trade runs for money—not a part of Roddenberry's Star Trek.

Concerning roleplay, some exists, but with players so spread out, it's less than I've seen on similar games. To the game's credit, there is a wide variety of canon races, but they're also mixed with overpowered and adult-oriented admin creations called the Unity (who all go about in fetish-wear and collars) and the Tyrix (who spew psychadelic light and eat Borg). These, when they show up, are certainly played by admin, and their twinkish levels of power are extremely disruptive, as any 'regular' players immediately become irrelevant to the scene.

In summary, this Star Trek roleplaying game really isn't Star Trek, and there really isn't much in the way of roleplay. With the exception of Niner, admin neither generate roleplay nor allow players to do so in any significant way. I have watched them retcon scenes of those who tried. The game's leaders have no management skills and know only how to demand obedience with threats. New players rarely find anything to keep them interested longer than a month or two before they either stop connecting or get chased off by leaders who don't have patience for them.

There may be 20 years of game history here, but that's become a liability rather than an asset. It doesn't encourage RP; it limits it. In my opinion, potential players should keep searching. This is not the Star Trek RPG you're looking for. If you decide to try the game anyway, be prepared for everything I've listed above, as well as an extreme learning curve of more than 100 potential commands and strategies needed for flying, trading, and fighting.
