I can't wait until these machines top out and get so realistic that they can only expand in scope rather than detail. I'll probably be like 80 by the time that happens, but it's cool. At least there won't be any more debates.
In all seriousness, though, I often wonder what will happen when we do reach that point. What happens when GTA looks no different than if someone was walking down the street shooting, or if MK looked like someone getting their heart ripped out? Will some sort of watch dog put restrictions on just how realistic you can make these things? It's fascinating to me.
