I don't think it's any less of a sim in fact they've added more detail to it, they've just polished it far more than ever before and the polish will make it more playable than previous. I would add that it'll never be as immediate as Cod or Battlefield.
@Dirtbox Yeah it's definitely moved more towards the battlefield side of things. Not completely mind, there is a touch of 'simness' there, but it's a massive, massive improvement.
When I work out how to claim my alpha keys I'll sling one your way.
