It doesn't matter which Kirby game you are playing since every single one will warm the coldest of hearts. Out of the ones I've played Kirby 64 gets my vote for cutest game ever. In the random category of cute games that can be kinda violent Cubivore gets the top spot.
I'm rather sporadic with updating random games on the Wiki. But this week I've spent more time than I should have with filling out the Hyperdimension Neptunia: Producing Perfection page. Since it just came out this week I haven't filled out everything yet. But I'm pretty much done other than a few other story beats and if it has any other unlockables. Unless I decide to fill out the entire credit list.
If you can find any the Nintendo Adventure books are really unique. After all its not often you get to read a choose your own adventure book staring different Nintendo characters. As stated by other posters the Resident Evil novels by S.D. Perry do a pretty good job of novelizing the games.
