Q. Dude, paradoxes?! You know, grandfather paradox, units fighting side by side?
A. Paradoxes can exist, but since the window of time is limited (e.g., an 8 minute window) all events eventually fall off. A paradox will oscillate between its different states until one of the states reaches the edge of the time window, leaving the players locked into one of the two states. Example: in the case of the grandfather paradox (where you use a factory to build a tank, have the tank time travel to before it was built, and then use it to destroy the factory) you will play with the paradox until it ‘falls off’ the time window, at which point there is a 50/50 chance of either the tank lives and the factory is destroyed (because the tank destroyed the factory), or the factory remains and the tank goes back in time and is lost. All paradoxes are nicely resolved with time.
If this concept proves itself, it could be implemented on every game. Portal, cnc and wolf3d comes to my mind :) And speaking of time travel – do not forget to watch Lost .
