I'm sure ship variations are being held up by the lack of source material in the canon and complicated by any and all Cryptic designs needing blessings over at CBS/Paramount, but for now, can we at least see some expanded Klingon race options?
Some quick-and-easy additions below:
Terran Empire: A small but significant number of mirror-universe Terrans have begun to make footholds and alliances here in the prime-universe. Allying with and aiding the Klingon Empire is but one of many tactics employed by Terran command to divide the Federations attention and thin their defenses. Much like the Germans trying to back Japanese and Mexican forces in an effort to keep the United States busy at home in WWII, the Terrans are seeking, for now, to aid the Klingon Empire of THIS universe in keeping the Federation on its toes, and offering better chances at gaining a strong foothold in this universe.
Cardassian True Way: Not satisfied with the direction of their own government, no small number of Cardassian True Way fanatics have turned to outside aid in their ongoing campaign against the threat of non-cardassian influence on Cardassia. Continuing to see the Federation as the great threat to Cardassia, and much like the Terran Empire, True Way fanatics have offered their aid to the Kliongon Empire in exchange for concessions ensuring the solidarity and purity of Cardassia after the Federaton have been pushed out of the sector.
Human Augments: It has been clearly established that Human Augments are working with the Klingons in existing Federation PvE storyline quests.
Jem'Hadar remnant: a rare but growing number of Jem'Hadar have begun to trickle into Klingon space, seeking asylum from the Federation and offering their not-insignificant skills and talents to the Empire's cause.
I think the Chalnoth would make nice candidates for a new Klingon species. They're not part of a huge faction like the other races and they're very warlike. They're tough but disorganised, it'd be a glorious conquest and good addition to the empire.
Regardless of the validity of my particular choices (they were, after all, off the cuff), I'm merely suggesting that focusing on Klingon in the C-Store and the game for a bit (not missions, but all the other stuff that has come to Feds - uniform options, fixing mission issues (old blueside errors persist on redside PvE), letting us take off the collar, etc).
One of the quick-and-easy ways is to expand the Klingon side variety a little.
Ok, how about this then.
For 80 points, and identical to the existing Klingon Race, a TOS-era Klingon race. No head ridges or lobe, the mustache, all that.
