TFT and GURPS - where is the line between them?

[Kromm]

I played tons of both and never really saw TFT as anything but "the thing that was on SJ's mind before GURPS." Experience-wise, for me, playing TFT felt more like playing Tunnels & Trolls or another fast-and-easy fantasy RPG, while GURPS felt like playing a cousin of what would become known as Hero. You can see some turns of phrase, trait names, etc. in GURPS that originated in TFT, but that sort of bleed-through is inevitable when two works have the same author. In actual play, they never seemed much alike to me.
