If you have to ask, you can’t afford it.
A HEP game is special. They cost crazy money, because they are worth it. It will play better than it did when they pulled it out of the box. Therefore, it should never be about this or that with a HEP game. It should only be about HEP or not. So if it is a decision between things, get the other. If there is a grail game and you have cash to burn, get the HEP and love it.
