Just posting because this is now one of my favorite mods.
When i downloaded it, i didn't really look deeply into it, only skimmed through the first post of this thread, and simply thought the ships looked midline and well-sprited and that's it.
But the game integration is spot-on. Each ship, aside from fitting perfectly with vanilla, does something fun or interesting or useful, and is otherwise useful in your fleet without being OP. These ships actually *do* something and don't just shoot bullets. The retrofits from less useful ships make them even more satisfying. In addition to that the added hullmods once again add interesting gameplay. I got mining drones on my hyperions with 2 leftover OP and it's somehow fun to contemplate.
Next, i just discovered that building the first roider structure in a colony generates actual roider fleets, which actually locate asteroid belts in the system and mine them. It's exactly the kind of things that adds to the game's immersion without negatives.
