Wow, reading through all of these really hits home how many of those points the TT Games (with the exception of Worlds) don't follow in the slightest:
IMAGINATION: Nope, not in the slightest. As you sorta stated near the beginning, players are forced down a singular path towards the end of the level, and there's pretty much no leeway around that. No interesting ways to approach a situation besides what the devs are telling you to do, and nothing to really broaden your thoughts on the game's world.
CREATIVITY: Again, nope. As I said in the previous point, there's no real leeway around the game path already chosen for you by the devs. No, the character customiser doesn't sodding count.
FUN: By McJob's definition of feeling that you're actually getting somewhere through mastery... no, not really. Other than the faint feeling of achievement when you 100% a level, you never really feel like you're getting anywhere (which is why the game tries to throw completion percentages at you all the bloody time), especially game mechanic-wise. Chances are you'll be doing exactly the same things near the end of the game that you were at the start, and that gets boring pretty quickly.
LEARNING: Definitely, definitely not. Anyone who's ever touched TLMVG knows about how bad it dealt with teaching mechanics (it spent so much time barking orders at me that I thought I was in the army for a sec), and although the more recent games have tried to reduce this it's still present in a lotta places.
CARING: From a gameplay point of view, there really isn't that much care in-between titles. Strip away everything and all you have is a barebones set of mechanics strapped together to make a very samey game. However, literally every other area of TT shows tons and TONS of care, and it really comes across in the final product. Cutscenes? Still the greatest bit out of all the Lego games. Character dialogue? Apart from a few exceptions (TLMVG, looking at you), well-written and occasionally really bloody entertaining. Obscure references? Always the best. So yeah, everyone expect the gameplay guys are fuelling these games with pure love.
QUALITY: Definitely the one thing that TT is best at. Although I have many, many issues with the TT games, bad performance and crashing isn't one of them.
In summary, the TT games are like the videogame equivalent of a dumb action film: although they may not win awards for being the smartest or most revolutionary things out there, if you turn your brain off after a long day at work and switch one of 'em on, you'll be able to enjoy the dumb fun that they can provide if you don't think about them for too long. From a gameplay analysis point of view they're rubbish, but from a 'dumb fun' point of view they're inoffensive, occasionally neat and qualifies as entertainment... unless you think about it too much.
