I genuinely backed the game with the amount I have as I really wanted something like this made, I was drawn in by the potential and the fact that Wing Commander on the Amiga was possibly my first game I bought myself back in '95ish.
So my shuffle over the weekend was a reorganising of funds, I haven't invested any more since late 2015. I was looking for some ships that I could have some fun in, once I'd decided how much to back given the potential. I really liked the 325a & the avenger as single seat versatile fighters, and the cutlass blue as I like the limited edition nature and the general cutlass story always resonated with me, finally the connie was a toss up between a few other ships and really I wanted soemthing with a decent hold. All these ships have LTI due to the early backer nature.... you're correct in that I won't fly them all (and maybe not at all depending on how the 3.0 branch evolves) and I suspect I will spend most of my time in the cutlass, I had 'credit' to spend after backing so bought stuff.
I think most that have large quantities of ships did so because they bought in to the vision of the game rather than the actual ships... The ships are just a perk of backing, although its easy to see that they are the purpose behind backing... Perhaps looking back I might not have backed so much but then maybe I still would have... This is a genre I have played to death and miss it terribly!
