I've been a fan of the civilization series since II. However I haven't played all of them due to being busy at different points in my life. Didn't play VI for example, but I did enjoy V, some of the DLC for it was good IIRC.
I'm concerned about the pre-order push, and that there is going to be a Switch version. But it does look like it could be good? No way I'm pre-ordering, but would like something to look forward to.
Civ 7 will suck. I know Civ 5 is better (and most that have played 4 prefer it; but I'm too much of a graphics whore to go back to 4); but I've been playing 6 because wonders take up a tile and are visible.
Building tons of wonders in 5 is too boring in comparison to 6.
