I liked 6 more than 5, but I liked 4 out of all the games in the series so far.

FC5 had an absolutely lousy ending. It was so bad I immediately went and got New Dawn in an attempt to wash out the aftertaste of FC5 ending from my mouth. And New Dawn wasn't any better. Slightly, but not much.

FC6 is just generic, without anything groundbreaking or any sharp corners, and with some fun activities like fishing and hunting, and visually pleasing tropical paradise to run around in. Esposito was criminally misused though, the ending was still kinda crap (though nowhere near as bad as FC5) and the writing was trash as usual, an average 9-year-old with a box of crayons could have done better.

Between FC5 and FC6, I would go for FC6. But in the entire series, I would have stopped at FC4 and pretended the rest just never happened.
