I don't know if its related to this mod but its too easy to build massive strike-craft and bomber squads and the game constantly crashes if 2 large fleets collide...
Well that's always been true of my mod. The anti-fighter frigates on all sides have been adjusted though to better combat this threat. Fighters in particular are extremely deadly to bombers now because they flight behavior has been somewhat adjusted. I haven't yet encountered a crash like you said. For my fix list I'm putting together I'll add on to increase the tactical slots used by hangar defenses so that there will be less of them.
also the ships speeds are way too slow in my opinion.
on larger maps it takes ages to move fleets.
any fight will be long lost (or won) before backup can reach the place.
Well that's kinds of the whole point. In vanilla sins, you could never launched a surprise attack because reinforcements could arrive so quickly. Offensive moves require preparation now. You should invest more into scouts to locate where the enemy fleets are so you know when to attack. With the huge amount of planetary defenses you can build, it should buy you plenty of time to get reinforcements in. I remember when I had 65 squadrons of strike craft sieging the defenses of an enemy planet, it took like 10 minutes before you could see a significant gap in the enemy's defenses because the fighters were taking out a lot of my bombers. So having fleets in defensive positions is far more important. The reduced speed also means you get more time to pick apart an enemy fleet. In all battles, historic and present, armies have always suffered the heaviest losses when in full retreat. This wasn't so in Sins. You could just hit the retreat button and the whole fleet would high tail it out of there usually suffering minimal casualties. I believe that you should do a strategic retreat. You retreat your forces in phases.
I noticed that the Akkan Class Battlecruiser has better stats than the Marza Class Dreadnought. Battlecruisers usaly are weaker then dreadnougts...
I increased the stats of all capital ships from vanilla Sins by the same ratio. Who says battlecruisers are supposed to be weaker than dreadnoughts anyways? I think in actual combat, the Marza is still stronger than the Akkan.
Icedude, are you planning on merging your mod with Sins Plus? Uzzi's mod.
Yes. I have wednesday afternoon free to work on it. I should have it out then as long as there aren't any problems, along with a few balance changes and changes to the leveling system for capital ships.
