*The beam-related specials stack too well in this game, especially those later ones.
*Certain specials like multi-wave jammer get very bulky for larger ships and seem pretty situational despite spending time with research. *heavy mount is extremely good and is one of the beam mods that seem to give beams (especially multi-proc beams) an edge over missiles. If bombing chances start at 50%, 65%, 80%, 95% with the post-neutronium bomb having a space reduction, the progression would feel more noticeable and more appropriate against increasingly tough planetary shields. *Bombs do not progress as much as I would hope, particularly in terms of colony bombardment, making it an unappealing choice. Maybe heavy and auto-fire could be mutually exclusive. I'm pretty sure it is intentional that these multi-shot weapons have extreme piercing ratings, but these weapons are also surprisingly good at destroying shields of their technology tier (ENV and heavy mod), their supposed weakness. *The progression of beams halfway through seem a bit unbalanced in terms of progression with multi-shot beams (plasma especially) coming out ahead of one-shot (phasor/gauss) and other weapon types. *I like the fact beam weapons are useful from early on (neutron blaster or even laser cannon), thus players have a choice on whether to use missiles vs cannons
MASTER OF ORION CONQUER THE STARS MODS MOD
From what I can tell, this mod is mainly about balance rather than a game-changing expansion and the game plays really really well. I started playing Master of Orion with 5X + UCP, thus I don't have the experience of comparing your mod against the regular unmodded game other than reading extensive documentation prior to buying the game.
