Hey there Stardock and fellow space captains!
I got Entrenchment up and running today, no problems for me, and I think you guys did an awesome job! All the new ships/techs/structures/and graphical improvements really add depth to the game, and as a person who has played Sins quite a bit, I think they were all well implemented.
I did encounter a few bugs however:
-Main Menu Music: Not a bug, but I personally preferred the old music better and would probabaly only want it changed if a new track was made specifically for the menu.
-Choosing to play as "Random" always picks the Advent: I tried this about 5 times in a row and everytime I picked to play as random the game chose for me to play as the Advent.
-Confusing Tech Info: The "Enduring Devotion" technology's hover-over text is hard to follow. I would type something like: "...which prevents hostile forces from destroying or conquring the planet which the starbase orbits."
-Repair Platform (Advent): In my opinion, the repair platform would be better off under the "Security" tech tree as it is used for fortification more than combat.
-Mines: I find the mine system to be a bit confusing and possibly too powerful for players who like to spam. It took me a while to figure out how to move and fortify them, and I ended up with many right outside my hangers. Also, a player could theoretically fill his/her entire well with them if they chose to build only hangers (Perhaps a mine well cap could be implemented). I also think mines should still be buildable even if you have the maximum number of strikecraft constructed.
-Advent Laser Platforms Tech: The Advent's upgrade for their laser platforms says that they give a sheild boost as well as an attack bonus to other platforms withing their radius, however the info card for the ability claims that it only gives an attack bonus.
-"Stunned" Ships are not attackable (Advent): When I used my capital ships ability to stun an enemy's capital ship (sorry can't remember the name of the ability lol), I was unable to attack it while it was stunned. I'm not sure if this was intended or not, but I thought I should point it out.
-Advent Starbase Twitches: After building my first starbase, I noticed that it only twitches left and right rather than rotate, which I assume it is trying to do.
-Advent Trade Ports: If I buy the Trade Port technology I am able to build them before the technology is finished being researched.
-Starbase Attack Range: This isn't a bug, but I noticed that the Advent star base, and perhaps all of them, have very small attack ranges even when fully upgraded. I would almost prefer it if the bases had large attack ranges, but weaker weapons. I know they have technologies that prevent the planet from being conquered while they are in the gravity well, but it just seems kind of un-epic for them to hardly be able to engage.
-Slow Recovery: After playing Entrenchment, it takes my notebook quite a while before it is usable again, even though my Vista guages show that nothing is going on. I have quite a powerful notebook and even after playing Crysis/Warhead my notebook does not take that long.
All in all however, I love the expansion and can't wait for the final release! Great job!
