Hello,
In the years since KH 1 was first released, we've definitely seen interesting ways to alter the various weapon strengths, to varying success. The original had you receive keychains that are reminiscent of places and characters you would meet on your journey, while the sequel gave them abilities that more or less established some as better than others. Re:coded was the first to really break the mold and allow every keyblade to be viable late game (to mixed success). With each upgrade, you gain access to more abilities in your clock gauge, allowing you to gradually get stronger before the finishing move. KH 3 takes things in a different direction, allowing you to upgrade keyblades that you get (even the Kingdom Key) with materials that can be farmed in the lanes between and on your adventure, granting stat boosts and abilities). With this in mind, the future of the series is leaning more towards the chance that this will be a constant kept throughout the games going forward in one way or another. But the question is, what do you prefer?
Me personally, I'd prefer the Re:coded method of increasing strength based on foes slain. Even though Re:coded was another KH 1 rehash (and a very poor attempt at that, seriously, no Neverland?) the idea behind the overclock system is admittedly pretty interesting. Even the naming conventions of the various upgrades are surprisingly inventive (various periodic table metal names for metal chocobo, earth wind and sky for oblivion, etc.) and incentivize you to keep using the keyblade to it's maximum level. Arguably it does incentivize you to farm in areas repeatedly to upgrade them, and each keyblade could be easily leveled to max as soon as you recieve it, but it's the thought that counts.
