I'm adding my voice for Swords of the Serpentine, my new go-to game to scratch my fantasy itch.
My main - and totally personnal - issue with D&D and F20 games are that they're way too heavily combat oriented. So okay, from time to time, I enjoy running a good 13th Age game, but I know that the main focus of our adventures would mainly revolve around fights.
With Swords of the Serpentine, there's first and foremost investigation scenes, as it's what the GUMSHOE system is mainly about, and there can be combat scenes too. The system was tweaked quite well to run nice fights.
Cherry on the cake, this game works wonderfully well with a 1 GM - 1 player table. The game I'm currently running with my player has even a nice Cadfael / The Name of the Rose feel, something which I'm not sure we could have properly experienced with an F20 game.
