HARD
Especially running it by yourself.. Oi. And voice actors? Hard to come by the good ones..
If you ever have auditions for your online productions; You're better off scouting out for them instead of them coming to you; ehehe.. Yeah.. lots of.. *ahem* Well.. they're talented, just some tend to stress their vocals beyond their normal capacities. And yeah.
Not much else I can say.. Though I do plan on kicking off the recording process in about 2 months for LotA. Which is one of my biggest productions ever. Very time consuming.
