Some things I noticed tonight:
Orcas sound like whales.
The headlights on the FdL have convergence shadows (the nose of the FdL gets in the way a bit).
Apparently it’s NOT pronounced “Friendship Drive”.
The insignia on your commander shoulder appears to reflect your rank.
It’s much easier to shoot people when you’re not hitting 10FPS in combat.
[Edit] And I’ve finally worked out what people meant by ‘Systems sound different’.
