Not an idea aiming to improve/change the gameplay or anything (hence the FUN tag).
Basically, allow the spectators to spawn in a predefined spot in a map with a command.
The original idea is from uBP server. Spectators were able to spawn as grangers in rooms outside of a map. (Example: Karith’s sky, which was also a shit idea because they would spit on players. The idea was really cool but the spawn points sucked ass.)
From there I thought of a few ways we can tweak this. First we could have specs be able to roam around in the map, but be invisible to/nonsolid/unable to attack players, only other spectators. As PINK grangers, obviously.
Second would be, we could have spawns in a room outside of the map as it originally was. Except that future maps could take advantage of that feature and propose an obstacle course for spectators, for example. Or a room with TVs displaying areas from the map, with a couch and pop corn. Or a granger fighting arena. Or [insert infinite amount of cool stuff you can do with that].
Another idea would be to make the spectator grangers able to build their very own couches & shit.
