[MENTION=49929]Scott DeWar[/MENTION] - Welcome back! Glad you're not dead.

[MENTION=51271]Voda Vosa[/MENTION] - side note, I think you got mistranslated, it's generally referred to as Occam's
Razor, not
Blade. I know that they're basically the same thing, but.. *shrug*
And on that note, Occam's razor isn't just 'simpler is better', and is rarely used in science as anything more than a guideline akin to "KISS" (Keep It Simple, Stupid).
This is because Occam's razor tends to be rather harsh and overbearing in the way most people approach it, as it seems to demand that scientists accept the simplest possible explanation for existing data, regardless of the fact that time and again, science has found that future data tends to support more complex theories than those we currently accept.
Complexity and Time do seem to be the most obvious ones. I've adressed all the other issues in other games I've run, and that didn't help...
IMO, How rewarding a game is largely depends on how interesting the story is, and to me, power level often CAN be a major factor..
a lot of people point out the whole 'it's the character not the level'... but most of the good stories, in literature, tv, movie, games.. are about characters who are important, powerful.. characters who have an impact on the world around them, and the ability to instill change.
There's a reason our comics follow Batman instead of Alfred, why we watch shows about X-men and Avengers instead of Officer Johnson cleaning up around them.. why our video game characters tend to be the main protagonists instead of their side kicks.
The most interesting stories tend to be about important events, and the important people who participate in those events.
Sure, sometimes the average joe/slice of life stuff can be interesting, but more often than not we want to be following the adventures of people who are Extraordinary.
Star trek, star gate, etc - they're not just random people caught up in big events. They're about the best of the best.
Leverage(awesome show btw) - Is not a show about an average group of criminals who decide to turn robin hood, it's about the BEST (Or damn near best) in each of their fields.
Game of Thrones doesn't follow the common soldiers or even commanders, it focuses on the people who are Important to the story.
Hercules, Superheros, Greek Mythology, etc, etc,
They don't focus on the normal people b/c the normal people aren't as interesting.
Humanity has always liked stories about important people, b/c it's about escapism, wish fulfillment, fantasy.. about something BIGGER. Super heroes, legends, ancient mythology.. this isn't anything new.
You don't hear many ancient stories about Hercules' friend Jared the sheep-shearer. Sure he may have a well-written backstory, but if we assume that Hercules had the same effort put into his...
I see so many people who seem to think that high-power means low-character development.. If someone doesn't put as much time into the high powered characters development as you did the lower one, then yes the character won't be as interesting as he could be.. but that's not a function of the power level, that's 100% based on how much time the person wants to put into writing backstory/personality. (As you've all said, Complexity and Time are the major problems)
YES, the characters are VERY important - but I've found that higher power makes it EASIER to make interesting characters (And speaking from a *usually DM* standpoint, interesting STORIES).. they've had more time to establish themselves, there's more in their past to call upon, they have amazing powers that set them apart. They can deal with things on a grander stage.. the story is less about stopping the bandits from waylaying the carriages (Which granted, can be an amusing story), they're more interested in saving the nation from the mighty thralaxar, ancient red wyrm who's been terrorizing the countryside.
To me, that sounds more fun..
And IMO, dragonball wasn't low level except in comparison to dbz, which is kinda like saying level 16 characters are low level when compared to level 40...
As far as being more relatable.. I don't know, I'm interested in the characters of Captain Kirk/Picard, General O'neil, Batman, Wolverine, Angel(from Whedon's Tv series), Chuck, Dr House, Dexter, John Connor, John McClane, Jack Sparrow, Skywalker, Nikita, Neo, Riddick, Megamind, Goliath(Gargoyles), V(Vendetta), Cloud, Jim Raynor, Thrall, et all..
