I think Civ VI is the best civ game so far and R&F added greatly to it. The addition of the loyalty system is one of the best things ever, as well as the vanilla version's spreading of districts and wonders on the map. I played IV and really liked it, although I hated stacks of doom; and I thoroughly enjoyed V, especially after its being fully developed with BNW. But I think VI was best out of the box (better than IV or V); greatly improved with R&F; and I can only imagine what it will be like with possible diplomatic and economic victory options [think something like enhanced World Congress from V and enhanced corporations from IV]. I'm not a 'hard core' player in the sense that I strive for the quickest victory possible or play in the most optimal manner. I always play my games through to the end and always play the 'hand' I'm dealt. I use specific civ for my civ, to ensure that I play through each one [just now finishing the vanilla and dlc civs, on the last one in my current game, and haven't started using the expansion civs]; play standard or large continents, as opposed to trying to use something that adds to a civs specific strengths; and usually take 2-3 weeks to complete a game. I think I have about 1,500-1,600 hours in VI so far, but that's not technically accurate, since I also tend to watch TV while I'm playing (finished about 2 turns during a 1 1/2 hour Olympic event the other night) and often leave the game on while I doing something else [had 5-6k hours in V]. I put all this in because I think I'm closer to the 'average' civ player than probably most people who spend significant time on this forum. The bottom line is, I love this iteration of the civ series, liking/enjoying it more than any of the prior ones. But as with everyone who posts here, we all have so many different things that make something enjoyable or not, that it ultimately just boils down to our own prejudices/likes/dislikes.
