In most RPG's, and thus in most people's opinions, I see that they think that choosing a class at beginning is like choosing your past and leveling up is gaining more experience. From logical standpoint, that makes sense.
However, there is a certain thing that bothers me about this: how can you become so skilled in so little time?
That is: people in these World's practice just one skill for DECADES to reach 75% of it yet characters in most RPG's need just a year to reach 100%? In TES games, it may be more years but in most cases, you will master many skills in less then 3 years of time. Isn't that kinda... illogical and non-immersible?
So I thought about what makes more sense and came to a conclusion that TES system of leveling up makes more sense when you look at it as mainly regaining experience rather then gaining. That is, rather then becoming better with a long sword, it is more like whenever my skill increases, it is "Yes, I used to do it like this...". A year or two may not be enough to master your skills, but I think it is good enough, for a person who spent years in prison, to remember the old days and just how he used those skills.
So since this is the Skyrim forum, I look at how Skyrim fits with this:
While starting with no class and all skills (presumably) equal may be a bit weird and some people claim that it restricts your RP-ing, I'd say it doesn't restrict you at all. Even the best Knight ever would need a bit of time to get back in shape, especially if he is skilled in more then one thing. Since Skyrim's Leveling system is slower the more skills you use and limited number of Perks (every character can have max. 50 perks from total of 200+), I think it allows you to create a lot of different characters with any kind of background.
End of random rambling of a guy who has nothing better to do (actually he has, but he is just too lazy ). So vote, reply, comment, flame or just let the tread fall into Oblivion (hopefully not into Coldharbour... Molag Bal is a scary guy -_-)
