I started playing it in 2007 up until about 2012 maybe. Through 2009 I was unemployed for most of that year and some of the next, lived by myself at the time I wouldn't even want to hazzard a guess at how many hours.
I was in Pandemic Legion for the last few years, had 2 main accounts and a third although I didn't always sub that one.
It's my game of all time, no doubt. No other game comes close.
But......you need to put the hours in to get the most out of it, you can't just pick it up and drop it down, so when I moved in with the now wife I basically stopped playing it.
But the game was good between those years imo, right at the end basically when I quit they allowed Intcerptors to warp in bubbles and some other **** like that to try and make it more noob friendly. It ruined a lot of my solo PvP strategy and just set couldn't be bothered to adapt anymore. I shudder to think what has changed since.
No idea if it's still possible but we worked out how to run plexes in null sec in ships with signature radiuses so small they couldn't scan you, man we used to troll them in local.
Dumbasses haha.
Got on a few titan kills, that's probably common now, when I started playing in 2007 they were few and far between, I think it was reported only 6 in the entire game.
My alt had a carrier. Again that's probably common now.
But no other game has come close to the highs and lows, interaction and strategy needed.
