Ali Hillis is super nice! I met her at a local convention (Anime Weekend Atlanta). Most anime and game conventions now have signings like that. Usually you have to pay a fee, but that's fairly common now. She's very down to earth though. I mentioned that I had just finished playing World of Final Fantasy and how I loved chibi Lightning and we talked about that for a minute while she signed the artwork.
The next day she had an early panel, like 11 am, and it was the last day of the con so not that many people were there, and instead of sitting up on the stage, she brought the microphone down and sat close to the small group of us that was there in a more personal setting.
I got another autograph actually because that same day I waited to get one from Laura Bailey (she did Serah's voice in the FFXIII games) and once I got that, Ali's line was almost gone so I went back and had her sign the same artwork that Laura signed, and we talked about how there was a Final Fantasy concert at the con that day and how good the music was in the FFXIII series. Ali also mentioned that more Lightning was on the way, and at her earlier panel she had talked about Dissidia and the mobile games so I'm hoping she was referring to yet another new game.
I probably spent at least $70 just to see her but it was totally worth it.
Somewhat related but I have a video (http://sword0fstorms.tumblr.com/post/166022192761/voice-actor-panel-awa-2017-featuring-feodor-chin
) of Ali, Laura, Jennifer Hale, and Feodor Chin (the voice of Zenyatta from Overwatch) from a panel they did, too.
This year at Momocon there's a lot of voice actors I'm going to try and meet: Lucie Pohl (Mercy from Overwatch), Jen Cohn (Pharah from Overwatch), Crispin Freeman (Regal from Tales of Symphonia/Winston from Overwatch), and Kari Wahlgren (Raine from Tales of Symphonia).
