Maybe for another project. I doubt he'll change his mindset about this one.
To be honest, I prefer him working alone, I have seen how Mrdots, for example, gets into many kinks and fetishes after a certain guy joined his team, it will kill me to see dpc have the same fate.
But at the same time, I know it will happen someday, just hope the guys that join him don't end up changing his games, not that dpc will allow such... but you never know.
Holy Bacchus I'm not so sure that he will never get help, I think he will at some point.
Because that is how the industry work.... times change everything and at some point, there will be lots of teams doing games with a lot of renders to top him, something that he won't be able to match alone.
