Much like the story above, some of us that played when the game was first on the MSN Internet Gaming Zone would start out a game with the intention of one massive battle at day 1,000 or so, throw it on fast and split the galaxy up, Rebs on one side Imps on the other. Then it was mostly about how many fighters you could serve up, insane amounts of lag back on 56k modems. =o) Honestly, the longest fights I can recall are using one Carrack Light Cruiser vs. an Alliance Dreadnaught or Bulk Cruiser. As long as you keep a Carrack moving in what was eventually called a "Carrack Dance" by some, you will ever so slowly prevail as the Imperial Admiral. The Carrack's shield recharge just wins out over time as long as it's not getting pounded the whole battle, by moving it in and out of enemy weapons range, you slowly gain an edge. The direct answer to your question, I think the longest I've ever fought a human player in one battle is just under two hours, and the most frustrating thing of all was that right as we came out of combat, we had a Reb.exe error, lol.
