Cool. I think I'd been there once, but I'd forgotten about it. I now remember picking up the "Seven of Nine" and "Arnold Schwartzeneger" voice packs there.
You know, another good potential voice pack would probably be a Whoopi Goldberg voice pak. Here are two good examples.
"And you deserve it, ***hole, and that's the truth!" (Jumpin' Jack Flash, when she was drugged)
"...I really gotta stop doing this." (Burglar, when she's working and you learn that she doesn't even like the work)
