While the TIEV does have comparable shield rating with the Yummi on an order-of-magnitude basis (maybe even substantially weaker), Derran and Wes makes some very good points.
This thing is a metal box the size of an apartment building, not a kilometer-long space-faring battleship. Many of the technologies that allows the YSA ships to have their insane power outputs would be infeasible or less efficient at this size.
I don't want Yori to think we are picking on him or anything. It's just that past experience has taught us to be very careful with the numbers, for the sake of game balance, realism, and playability.
And like Wes said, start slow, start small. Why?
1. Nova Corp. is a start-up. It won't have the most talented scientists as employees and shouldn't have access to the latest technology of the other, more established corps.
2. It won't have much money, and a license to exclusive mining rights to the Fenyar Cloud has got to cost a pretty penny. On top of that, mining the cloud is dangerous, slow work.
3. Nova Corp. would be competing in the same market with Ketsurui Fleet Yards, Kessaku Electronics, Wicked-Arms, Phoenix Arms, Feisar Arms, and imports from the Draconian League. Being the new-comer, it can't possibly be very successful at first.
4. The Fenyar Cloud is currently at the edge of YSA territory, at a time when military resources are spread thin. Nova Corp. would end up spending a lot of precious resouces defending itself from pirate raids and the occasional SMX scout ship.
Right now, Nova Corp.'s best bet would be to exploit the niche markets left empty by the departure of the QelNoran Industrial Sector. Civilian ships and vehicles should be in high demand right now.
Nova Corp. could also compensate for the inferior quality of its products by offering better cost efficiency (read: cheaper). The Nepleslian Police experiences high equipment "turnover" rates, and would very likely be interested in cheaper weapons. The Elysian Celestial Navy could also use such products to re-equip its legions of Seraphs.
Nova Corp.'s product line looks good right now, but more lower-end weapons are needed.
