Pre-loaded copies of Paper Mario Color Splash can be played right now.
Apparently people have beat it, and say its 20-22hours long.
Its super easy mode entire way though. Battles become trival and boring quick.
If judged for its charm, good level design, and as a "Mario point and click adventure game", a guy said he rated it a 6-7 out of 10.
So what a guy in neogaf says is a consensus now, right...
That guy should look up for the definition of "click and point adventure" btw.
"The player clicks to move their character around, interact with non-player characters, often initiating conversation trees with them, examine objects in the game's settings or with their character's item inventory. Many point-and-click games would include a list of on-screen verbs to describe specific actions in the manner of a text adventure, but newer games have used more context-sensitive user interface elements to reduce or eliminate this approach. Often, these games come down to collecting items for the character's inventory, and figuring where is the right time to use that item; the player would need to use clues from the visual elements of the game, descriptions of the various items, and dialogue from other characters to figure this out."
^ seems true enough.
Also there are point & click games with battle systems in them.
I think its fair enough for that dude to say it plays like a point & click adventure game.
