I may get flamed for this, but I am really disappointed with SPM.
Currently at world 8-1, and been playing it regularly for a few weeks now (about 25 hrs in).
The strong points: the gfx, the writing, some of the stories.
The bad points: the game design, the level design, inconsistent levels (and inconsistent gameplay)
...
I was going to write a deep analysis/review of the game - but maybe later.
It started as a 8.0/10, moved up to a 8.5/10 - but then gradually fell until around a score of 7.5/10.
Its probably the weakest Intelligent Systems game I have *ever* played, and does not live up to the "Paper Mario" name.
In some ways it reminds me of Sunshine (although not as brilliant or fun) - as if they ran out of resources and ideas part way through the game. It lacks balance and consistency.
A couple of the levels are brilliant - but too many are mediocre. The entire "combat" system is poorly designed, the platformy elements not well thought out, no real balance for most of the non-Mario characters, the Pixl system not well enough used, etc.
Has anyone else experienced a less than "as expected" experience with SPM? Its quite possible that my expectations were unreasonably high - as Thousand Year Door was my fav game from last generation, and Intelligent Systems my favourite developer.
