Comment below is not to detract from how awesome I think this release is. It is the best yet as it focuses most exclusively on the core parts of the original released game.
"- Added enhanced performance size 2 and 3 drive modules"
And thus why I have said since long that module ratings should start at zero and go up instead of starting at G and going to A where they max out. Or they need additional attributes. The baseline for foot-soldiers to Space Stations could be set, so hand-held weapons would be class 0 and go up from there. So now we already have A+ modules, or however they are designated (I'm still downloading, so can't check them out yet).
Would still love to see manufacturer specific modules with varying stats for equivalent equipment and some ship-specific modules (not just by size / class). This would add more color to the game. Do I put Holley Carburetors on the engine or keep the OEM ones?
The last bit for me is tech levels. Would like to see varying tech levels in the game. Everything is very homogenous now, every ship the same generic capabilities at a single technology iteration in time. Alien cultures could have lower or higher tech levels. Ships in Elite could be 50 years old and on previous gen hardware. I know it will be a lot of work, but will add more flavor.
Several ways to approach this module aspect of the game. But I think Engineers are a bit of an artifice to enable the module differentiation rather than going with the above route. They could still be in game but much more rare and difficult to reach. Oh well, design choices will never please everyone.
