I love levelling! Getting that little bubble dead center feels so good... (he says, as if he even owns a leveler)
But yeah, levelling up is so good that just about every genre has it now. It's a great way to change up the game.
It's not the only way, though. There's also the option to constantly reward the player with points and let them spend those whenever they want. That works great, too. Or you can have different things levelling up. If a character has three weapons that are each levelling up, that character can "respec" simply by swapping out weapons.
What didn't work so well was learn-by-doing, as in the pre-Skyrim Elder Scrolls days. It sounds great because it's a lot more realistic. How's a thief supposed to get better at climbing walls without even trying to climb any walls!? Unfortunately, it tends to lead to players doing whatever they want to be good at over and over in the safest environment they can find, like constantly jumping around town to bump up the athletics skill. In other words, people start practicing. It's so real, it made progression as boring as it is in real life!
Build Guides: That's like having a walk-through guide! I might read some for tips on a second play-through, or if I think I'm doing it badly on a first play-through, but my builds are too much of a creative expression to just take somebody else's build verbatim.

The ultimate character builder's dream game - and it isn't even an RPG (even if it says it is)! It's more like XCOM with a JRPG story. HUNDREDS of skills to find and use! Hundreds of special bonuses for slotting in certain sets of skills. About a dozen characters to pick from (eventually) and you can bring up to 8, so the synergy potential is massive.
Also available: - Pathfinder: Kingmaker - Royal Ascension DLC - Pathfinder: Kingmake

Your characters do level up, but that's not the important thing. The powers your characters get are almost all gained from little gems called materia, and those level up as well. Some are simple ones that cast increasingly deadly elemental attacks, heals, or status effects. Some add abilities to your character like making them jump in front of other characters to take damage for them. Still others alter the effects of other materia. And, being little gems you slot into your weapons and armor, you can easily move them around from character to character. So, it isn't so much the characters levelling up in this game, but the powers themselves gaining levels! The newer games have the same system, but they aren't as pure an example.
