To me, III was the sweet spot. IV added some interesting ideas, and could have worked really well, but the interface and design was an ugly mess. V sorted the interface and design, but seemed a very shallow shadow of the former game. It also seemed to want a ludicrous amount of resources - a simple isometric view that always seemed to need as much PC power as Far Cry. Games bogged down to plain slow from mid game on - too much turn waiting, not enough playing. I gave up on V quicker than any previous Civ and spent most of my Civ time since in Europa Universalis. If I buy VI at all it'll be after it's been out long enough to have plenty of real reviews and opinions on how well they did. Some of the ideas sound interesting, but the real test is how the balance ends up. Don't like the cutesy graphics style though, so would hope for a mod or post-processing fix.
