Believable comes from few things, but mostly from obeying laws of physics and from creating believable characters personality that is logical and not forced in to plot movers. Graphics is important part of immersion, but if it's only 'realistic' thing, then overall experience is flat.
@Dark_Mits @Thrazewolf @BOWAlexia No, back in the days sega had blast processing... ;) and atari and amiga fans were meeting up every weekend and beat up the crap out of each other. Seriously ;)
If you want to get rid of violence you need to start teaching people empathy from youngest age. And also make psychology test throughout their education to see who might have psychopath genes and take care of that person.
