Star Wars Galaxies - the open world, the city building, the player housing, the ground and space vehicles, the player market, the world pvp. It was so much goodness. Broke all future games for me.
Oh man. Me too. The player market and pvp were the best. I loved how there were battles to actually control territory. There were places you just couldn’t go unless you were covert. That game should have gotten so much more love back then.
