I love GalCiv II but I'm sad to say that from all the gameplay of the alpha and even your list of changes from each version is confirming my worry that III is not really that big of an update. Heck, you guys are even using the same old logos and opponent civs from the last game. Two of the bigger changes mentioned are strategic resources and the ideology tree, but even these are just rehashed features from games like Civ V. Why were strategic resources not in the last version for that matter. That concept has been around for years. And the ideology tree is just another social policy feature like in Civ V.
It would be nice if you tried to implement truly new, original features that make the game different. Not everyone loves the city states feature in Civ V but at least you could say that is a completely new feature to that series that really alters the entire world and gameplay experience. Where is that happening in Gal Civ III? Otherwise, you should not call this a sequel - it's just another expansion.
You have also really simplified the economic system in this game and taken away the unique aspects of II that made it stand out from other games, i.e., like the ability to reduce production spending to manage your economy. Now with that big circle, it looks like all you can do is adjust where the spending goes vs. each category.
Multiplayer? United Planet proposals? Again, all sounds like features we can find in other games and that should have been around years ago. I personally don't care about multiplayer but a lot do so you can have partial credit on that one.
It's probably too late for this game but I hope you guys are hearing some of this feedback to think about future projects. There are a ton of people commenting on the YouTube videos about how this game is not really looking very different from the last version.
And I'm sorry, but the hex map, even though I personally prefer it, is actually not doing a thing to change decisionmaking or overall experience in a game like this. If anything, it's just reducing the number of directions you can move your ships (now only 6, before with squares it was 8 directions).
