I tend to lose interest at high levels. You may have more options, but chances are you're just bumrushing everything, because you can. It also gets a bit retarded storywise because RPG worlds are lawless shitholes where everything can be solved with violence, yet you often can't use your massive power to just destroy everyone and everything between you and your objective.
This reminds me of a tourney I was watching in Ultima online. The contestants maxed everything they could, yet the fights consisted of running in circles slinging fireballs at each other. One of the guys beside me even says, "These guys have 63 spells but only use two".
