Sins of a Solar Empire is often described as a 4XRTS game, or a game that tried to merge the action and tactics packed gameplay of a Real time strategy game with the deep, complex, empire wide strategy of a 4X turn based game. It's up to debate whether Sins succeeded in this goal, but I think all can agree that of the 4Xs of "explore, expand, exploit, and exterminate", Sins is much more focused on the exterminate than on the others. This mod seeks to give more depth to the other 3Xs of the game by adding additional game elements or refining the existing ones to reward players who give more strategic thought to the non-combat side of the game. Combat will still be the center point of the game, but players will find that the non-combat options available will be much more rewarding. Spying, exploring, sabotage, diplomacy, culture, and economic development have all been added or changed in innovative new ways. Regardless of what you think Sins is, this is the 4XRTS it should have been.

Enhanced 4X Mod 1.74

Blog RSS Feed Report abuse Latest News: Small Hotfix for E4X and Interregnum

1 comment by GoaFan77 on Jul 29th, 2014

Hello E4X and Interregnum players,

I've released a small, optional hotfix today that applies to both mods. An issue was discovered that caused the AI to occasionally stall and do very little. This was caused by a mostly behind the scenes change related to uncolonizeable planets made in Enhanced 4X version 1.7 (in part to test the ground for an unfinished Interregnum feature), but was not noticed at the time because of the Rebellion 1.8 patch had changed the AI as well.

This hotfix for the most part reverts that change, however this has the side effects of getting rid of the uncolonizeable planets' planet bonuses as well as the pirate trade station random encounter. The random trade stations will hopefully be back in the next full release, but the neutral planet bonuses were just not meant to be. I believe the future Interregnum feature can be accomplished in a different way that will not cause the AI problems.

To install this hotfix, simply extract the download. In that folder, there will be two folders, one which contains files for updating the Enhanced 4X Mod 1.73 and one for Interregnum. Simply copy the files in these folders and paste them to the GameInfo folder of the corresponding mod. Interregnum players will need to copy both sets of files into the correct mod. Additional instructions are included in a text file in the download.

I apologize for the inconvenience, and if you haven't had any problem with the AI you're free to wait for the next major release.

I have reduced the fighter counts of each squadron already as well as increased carrier fleet supply usage by 50%, but for the moment there is no option to reduce it further.

Howdy GoA! How goes the work on this fine mod + Interregnum?

I'd agree that the only con of this mod is that AI is sorta passive. Ok I am not using the newest version(idk if I use ,72 or ,73), but still. If I don't go to unfair or higher they mostly do nothing. Hard AI should be more difficult imo. I even set it to "Agressor" and nothing - the AI bunkers. But if I set it to Defensive it starts attacking! What gives?

I know that you can't really do anything about this, but it would be VERY nice if we could play vs AI in the full glory of this fine mod. Add in Real Capital Ships and perhaps Faster combat minimod... LOVE IT!

Yeah, I'm afraid the relative AI change was something Stardock made, I cannot undo it with this mod. However, if you play the latest version, there is an new minimod called "Enhanced AI" that does what I can to give targeted bonuses to the AI to get them to play better, but are not direct economic or military benefits; the goal being it shouldn't feel like the AI is getting additional cheats.

Since it was just released last update its still pretty basic and this point, but hey, it might help and will likely get better over time as it gets tested by more players and I add improvements.

The main reason for the early slow down is simply sometimes the AI mismanages its resources badly, or decides it needs to save up for something expensive when it shouldn't etc. On harder difficulties this isn't as noticeable since the increased AI resource cheats means it usually has the means to build something at all times, but since Stardock decreased the resource cheat, even hard can suffer from this problem now (normal and easy could always do this).

I have a bit of a problem. I am running v1.82.5006 with both of the DLCs and the game crashes whenever i try to apply the mod. The checksum is the same with the one in the Description and im stumped. I have a 5gb download limit so I don't exactaly want to download the mod again if it's just gonna do this again. Any suggestions?

This would be Enhanced 4X 1.74's checksum correct?

One guy had crashes on start up because he made some unusual manual changes to the settings file. Especially if you made any changes to it with notepad, I'd try moving the file to another directory (the game will make a new one on restart, and if it doesn't help you can move it pack to preserve your settings).

Hello dear modders,

I've got a question,
Does this mod change the vanilla combat system in any way? Because I really hate this "Unit gets hit by a projectile that's half the size of itself and loses only 1% health"-crap of the vanilla game. And in case your mod doesn't Change it, do u know any Rebellion mod which does exactly this?
looking forward to your answer and to try this mod.

Well, there is the faster combat minimod that increases all ships damage by 50%. I'm assuming your main problem there is the combat taking too long.
