I'd be a liar if I said I've played like, hundreds of fangames and romhacks, but I've played a good few.
I genuinely do not think anything could ever beat this game. I've completed both Paragon and Renegade and have never been more INVESTED in a story of a fangame in my life. >!(ESPECIALLY the School of Nightmares arc and most of the Renegade Karma Files plot.)!< If you had told me I'd play 1000+ hours of a fangame a couples years ago, I'd call you insane.
Truly my only regret is not discovering the game sooner. I started about a month after v13.5 released after simply looking up good fangames to play, and would play it, drop it, play it, drop it, until finally beating pretty much everything.
I want to personally get a beer with everyone involved in development.
