Based on the coverage from
Dan Kanemitsu's blog, that's not true:
Since the bill as written covers "pictures" and "animation" (but not photography or live-action film) it would seem to also cover computer-illustrated-or-animated content contained within video games as well.
As best I can tell from this write-up, the bill does not in fact create any additional restrictions regarding homosexuality, but it would potentially make any works including themes of rape or incest "adults only" even if no explicit content is included as long as they fall into the extraordinarily vague standard for being "unjustifiably glorified or exaggerated."
