Other eras were considered, but it would be very tough to pull off, because TNG had the most variety of canon ships. I considered a TOS era mod, but it would have been based more on "Starfleet Battles (aka starfleet command) than Trek itself. Again due to the lack of canon material. We use non canon from FASA and SFC to fill the gaps in SoA 2, and we are making up stuff as we go. SoA 2 is based closest to DS-9, but takes place intentionally after Trek XI starts (2388). We are ignoring the events of Trek XI for this mod, because it complicates things WAY too much to include them. You do want romulus, and vulcan to still exist dont you?
"If" we accepted the events of Trek XI then everything from TOS forward would be erased from existance. Due to a paradox of epic proportions thanks to Nero, err or should i say Spock.... Well he did invent the "red matter" that started that whole mess.
While we focus on a fictitious post TNG era that never existed, there is absolutely nothing stopping anyone from using what we have done here (code wise) as a guide to create a trek mod in another era. In fact i encourage it. You will just have to provide your own models (be it yours or permissions from a 3rd party). All of ours are spoken for.
Orions will be the pirates. Free time willing (crosses fingers) i can conjur up a mesh or 2
Planetary defenders. Again free time willing will be various "ships of the week" we saw in TNG including a ferengi marauder, and a Sona battleship.
Ships we will NOT include in this mod just to remove ALL doubt. They wont be included due to ether being "uber", or being absurd. or being from Voyager, or all of the above. The Scimitar (fits both the uber, and the absurd catagories). The Prometheus, (Too uber, and its from Voyager. I HATE VOYAGER!). Any, and all "timeships" (again absurd, and all from Voyager... Did i mention that I HATE VOYAGER?). The Olympic (alternate timeline). The Galaxy X (alternate timeline). The Dauntless (alien ship, and its from Voyager.. nuff said).
No Delta quadrant races will be included with the exception of The Borg (see the above "I HATE VOYAGER" comments).
Yes I do hate Voyager, Dont get me started as to "why". I will just sum it up in 2 words.. KILLER B's. At least the Intrepid, and the Nova classes are in the mod (AFAIK they are the only ships from voyager that are). The first 3 seasons of Enterprise are also in the same category as Voyager (pure crap, and again KILLER B's), but at least the last season almost redeemed it. Pity it was too late to save the show. We do use "Alien" ships from Enterprise in the mod, but we will NOT use earth ships.
That is my point of view. I dont want to write a novel as to why i feel the way i do about voyager, or enterprise. Others worship the shows, and to each their own. The old school shows may have had cheesy fx, and no catsuited fake boobed bimbos, but at least they told a good story. Especially TNG.
