I think most people always just play the most recent one. as for what's actually better, i love the leader agendas; they make the leaders feel far more unique
Yeah, I think that the AI have a much bigger of a personality than civ 5. Also I love how you can’t play as tall in civ 6 and how each city can be more specialized in terms of gold, science , culture, faith, etc.
When it comes to the gameplay, I much prefer civ 5, but the graphics civ 6 is much better. It really depends on how you prefer to play the game though, so I'd suggest trying both before you buy either, again, I prefer civ 5 (mostly because of the builder changes they made between the two games)
^ the builder charges actually make sense. it's crazy that a builder from the stone age is capable of building windmills and whatnot.
What do you think?
