I do quite enjoy Kingdom Hearts.
Those of you who are still reading, thank you. My appreciation for the series has little to do with Disney or Final Fantasy, neither of which I particularly care for, but with the game itself as a whole: an engaging third person action game. I rather like this genre of games and find Kingdom Hearts to be one of the best, if for no other reason than sheer production values. There is a wide range of special moves (summons, limits, drives) to unleash and a great deal of options as far as playing style. But the most important part, and probably the reason I place Kingdom Hearts so highly, is the fantastic Gummi Ship mode.
In my erstwhile life, I did posses a great number of Lego brand building blocks. The most common thing I built with these blocks was spaceships. Lots and lots of spaceships. Almost exclusively, spaceships. My imagination ran the gamut from a range of simple three piece models for vast space wars, to a hulking behemoth armed with six rotating cannons, three missile platforms, and an emergency escape pod I rather liked. The Gummi Ship mode of Kingdom Hearts brings me back to these halcyon days, while animating my imagination that wasn't possible in plastic toy form. Only in this game is the level of customization at a point where I can recreate nearly every ship I can come up with in my imagination and actually play with them in an actual space shooting session.
But I could be wrong. Are there any other games that allow the same amount of creativity as this? I have no stipulations, I'm willing to try anything.
Edit: Hoping for this sort of thing, I bought THQ's "Drawn to Life" hoping for a similar experience. What I got was a mediocre platformer with a generic story and aggravating between world bits. It reminded me more of a flash game than a DS game.
