What I did was choosing Chrono as my favorite series and briefly explaining why (when the true favorite is Final Fantasy..) Then I wished for remakes or sequels to Parasite Eve 1/2, and Xenogears.
Fans choosing Final Fantasy or ports despite also appreciating other classic Square titles could take a lesson or two on craftiness. I'd take a new Chrono/PE/Xenogears game over a measly port anyday, and not voting for Final Fantasy will not stop Square from making them.
Yeah I pretty much did the same thing.
I also understated how often I play on mobile, because I know answering truthfully there would be counter productive to what I want Square Enix to focus on.
And I told them about the importance of DLC expansions after you've already gotten a satisfying full game experience (a satisfying beginning, middle and end), rather than have the DLC amend for that.
