As I said, this discussion has been dealt in every mmo there is and as a result, two mmo categories emerged;Then its tough, really. I can't play because I have a nerve injury but I'm not bent out of shape about it (or that I missed the last one, or the themed paints that get given away).
Unless you are running a competition (where you can insist these modules are banned) then the effect is marginal.
To me its like the reverb lasers ATR ships have- I view these special modules as things some players have managed to get.
-Either you offer advantages through REAL money, openly declare that you have a pay to win game model, and expect to have the corresponding player base, or..
-Offer only cosmetics, either with money, or as gameplay rewards, that only act as bragging rights, and do not offer a permanent advantage whatsoever.
Im pretty sure FDev is not living under a rock, and that they are not trying to invent a third mmo category here.
Thus I strongly believe that they plan to offer this kind of engineering in the near future, through other means such as rare special missions etc. and not lock players out forever.
