I like the hex

I thought I remembered a post that GalCiv IV wouldn't have squares or hexes?  Am I just making that up?  I thought maybe it was on the steam forums.  I wasn't sure how that would work, so glad to see the hexes are retained.  

I remember that version.  I've had all the versions, looking forward to #4

I don't like how you can't move in a straight line on the hexes. It's like a squiggle line snaking back and forth. Just a cosmetic detail but it looks silly to me.

I'm hoping we get an option to change from hexes to triangles just for the heck of it....  

Hexes are generally much better than squares for handling movement. The issue is diagonals. Squares have diagonals and it causes distance weirdness if diagonal moves are the same as straight moves. Hexes eliminate that entirely.

Admittedly, it's a fairly minor concern and wasn't a problem in older 4x games, but in general I've found hex-based movement to work out better overall.

No.

I have absolutely zero to base this on other than a feeling (and having been playing GC since maybe 93 or 94 on OS/2 before big blue screwed the pooch).

My gut feeling is that it won't have tiles at all.

Edit: Okay, let me clarify. It may have internalized "tiles" which might be one distance unit of measurement, but I don't think it'll have tiles in a traditional/conventional sense.

With today's GPUs and CPUs, memory speed and bus transfer rates, disk transfer rates (thank you USB 3.2, NVMe and SSD) 'tiles' are a legacy left over from board gaming. A handful of games have tried true 3d space simulations, but I honestly think in the last couple years we've gotten to the point where we could actually simulate on PCs a game playable multi-thousand body system in 3d. Which calls for something different in terms of navilocation.

I personally like hex better. It allows more freedom of movement in my opinion.

Hexes are just better (so long as the "squiggly movement" is handled).  1.4 for a diagonal move on squares (to make it fairly accurate) is more confusing.
