“Achron—Time Travel is Coming [1]”

Over a year ago I mused about making a computer game involving time travel
[2], but it seems, a group of programmers have gone ahead and made a game
where pieces can travel in time, and from the videos, it looks like they've
done a great job with the user interface.

> 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, or the factory remains
> and the tank was never created. All paradoxes are nicely resolved with
> time.

>  A. Yes you can, but not without consequences. It costs chronoenergy to
> command units from the past to travel further into the past, and obviously
> you use more chronoenergy to control more units in the past. Also you are
> using up your playing time to manage this instead of building units or
> controlling your armies. And finally, if the original 'parent' units are
> damaged, the time traveled version will wind up being damaged and if the
> original units are destroyed and don't travel back in time, you wind up
> undoing the entire cycle.

> Q. My head is exploding already. Are you sure this is easy?

> super quick to learn. It's like learning to use a DVR control to rewatch a

> you start using time travel it's really simple, but if you've never picked
> up a remote controller before, those play and 'next-chapter' buttons look
> scary. We've been play-testing for 4 years and have learned how to make
> this game accessible, taking people who never played an RTS before and have
> them effectively using time travel 5 minutes into the game. We do this by
> unveiling time travel gradually to the player, so you are not fully thrust
> into it right away, but can learn to play it one step at a time.
