Do the folks in Sims have to deal with invasions from various creatures and put up with the ones which already settled in the Yliakum? In here casual people are actually expected to have some fighting skills. That is what the setting says. Great heroes? Probably no. At least if what I heard is right, Talad aims for players to role-play "people", not invincible fighters.
First time I hear player character reaching fame and glory is actually interesting though. All experienced players and Game Masters I met think it's actually quite the contrary.
I said wannabe heroes that will be met lots of risks, because without risks it becomes a bit monotonous, don't you think? Once and if these people reach their goal, it's usually time to make new characters and start all over again. The long and risky road to power is what is interesting, not the fact of already being powerful, and it should be based on a multitude of quests instead of grinding mobs as well. There should be opportunities to people cross this "road", but after it was crossed, things should change to encourage them to stop right there(or perhaps even force them to do so) instead of griefing people with the "Evil Lord of Doom" or alike. For those who seek to play as people that already are powerful, there are the "Empire-building" strategy games, where it's all seamless and there is no griefing because you don't exerce your power over real players, except when you are in war with them. "Reaching fame and glory" usually only happens at the ending of single player RPGs, because after it, it becomes as dull as being "normal" people because the challenge vanishes.
Of course we could extend this more, giving people opportunities to corner markets and become rich and influent through businesses, competing with many other businessmen as well. Challenge does not need to be based on warfare.
And lastly, a "detective" path could open even more intesting perspectives, so I am definitively against possibilites being restricted to a "casual" person that occasionally have to fend some creatures and then return to routine. Of course all should start as "normal" people, but should have the chances of going beyond that. Either on business or warfare among other perspectives.
