What does that mean? I mean why not just play to lvl 10 or something if you want to play a normal person. What does level have to do with it? It took my players about 4 years (10 years game time) to get to level 10, so I know you can play a long, thorough, and fulfilling campaign at low to mid levels. If you want to go the demi-god route, look at Theros did it with supernatural gifts or grab them from the DMG and, boom, you have a little demi-god boost at level one and 20 levels to build on that.
However, none of those are epic player options were are talking about in this thread.
