As far as I know, no game on byond has been removed from hubs (yet!) due to excessive violence and/or gore yet, as opposed to that Hentai game we all know about (Then again, I don't know the whereabouts of that game that either had black people killing the KKK or vice versa neither, wasn't it called blackworld or something?...)
Anyways, as any seasoned gamer would know, even in the year 2010, the original Mortal Kombat for instance is still rated M for mature which arguably contains a lot less blood & gore than Dead Space in comparison. Maybe the ESRB is too lazy to adjust the rating?
With this said, I kinda notice bias(noes!) towards nudity versus blood (pretty much globally), but understandably, one can be more "creative" with blood than nudity and it's much easier to chalk it up to mindless time wasting. Unless you're pretty highly conservative, 2D blood/violence isn't usually seen as much of a threat to the impressionable youth nowadays though.
Back to the question at hand, do you think it's possible that something on Byond could be made so bloody/gory or in some kind of way offensive based on 2D graphics alone? I know no action has been taken against my game Splatter which purpose is purely mindless entertainment, but it's more likely that isn't the case because A) my artistic ability sucks and/or B) my game is hardly played enough to even be noticed (here's a screeny so you don't have to play it, although there are accompanying death sounds). While I (highly) appreciate that Byond allows blood & such in games (creative freedom is awesome), I wonder could there ever be a point attained where there is just too much to reflect well on the image of Byond. If not, someone should go make a graphically gorgeous, ridiculously bloody, yet fun game pronto...
P.S. I fully intend on using blood and whatnot in my projects (for the hell of it!) but as always, my mind began to wonder so I just had to pose the question to the masses. :D
