I've read an article in Igromania magazine that had Discovery as one of the most prominent mods of the time.
I started to play Freelancer completely disregarding unlawfuls and skipping most of the base rumours. It was mostly about pew pews in space and then the Nomad part kicked in and I got really interested. Past that point I mostly ignored the Houses and whatever story they had. Then I got to the secret systems and the game was essentially over. I did get the Titan for teh lulz after that.
Eventually I came here and met the Oracles, immediately jumping on the cultist train to bring back that feeling of wonder again. For a time I had a free pass to explore Nomicrons, a permacloak to snoop anywhere and there were enough people to RP with. It was fun while it lasted.
