It really annoys me when I somehow find out which races are playing before I make first contact with them because of a GNN announcement. (I think the trade income quarterly report lists all races in the game as well). I know this has been brought up in the past, but the addition of all these new unique galactic achievements some races can spit out almost instantly excaberates the situation. If you start a game with Thalans in it, for example, you'll know in the first couple of weeks once they get their hyperion whatchamacallit online. GNN should probably not cover achievements by races you haven't made contact with yet if you're playing with blind exploration.
