The spring engine has a feature called strategic zoom, which was blatantly copied from the supreme commander previews. Some people have found a useful way of using this to show full length games in a matter of minutes!! Under the moniker of dot wars xtaboi, Noruas and others have been recording videos of entire games on a single screen and then speeding them up for easy viewing!
Here are a few examples to get you started:
2 hour battle in 4 minutes 9 ffa – Dot Wars
Don’t Stop me now – Dot Wars
An Hour 1 vs. 1 – Dot Wars
Spring RTS: Dot Wars, 8v8 team game on DSI, 16x speed (HD)
