Sci-Fi: Startrek, Stargate, Starwars and Starcraft II & 1.
Letís say, that the Startrek, Stargate, Starwars and Starcraft universes are suddenly all connected within 2 Weeks at warp 9 of each other (The Next Generation math). Every race, faction and w/e is at their greatest peak in civilization plus technology with no illeffects of their storyline. (Like dying from clone degeneration) (Ascended beings and Q along with other omnipotent beings I forgot are not part of this.) How would this play out?
(If you are unaware of and not willing to google one or more of these combatants you may exclude them from your predictiction.)
They just became connected and become aware of one another but storyline alliances are intact.
Every faction (even human vs human) become part of a big free for all to rule the universe scenario.
