I actually kind of liked Sunshine better than Mario 64; but I was never the biggest Mario connoisseur. I thought there were some really neat mechanics with the water gun though and I would love to see it used again; either as a full game mechanic or even as some kind of temporary power-up.
I'm playing through The Path right now and, like any other art game, it gets its fair share of criticism. It's absolutely fucking brilliant though. I checked out the other Tale of Tales games around the same time I got the Path and they're kind of hit or miss (the Graveyard in particular is the most pretentious piece of bullshit I've ever seen; the only difference between playing the game and watching somebody play it on Youtube is whether or not you're holding the key to move forward). The Path is a real masterpiece though. With its surrealist imagery, feminist themes, and interpretive story, it really takes no shame in alienating 99.9999999999% of gamers right out the gate, but if you give it a chance you'll quickly find that whatever tedium there appears to be turns to curiosity and any confusion that might arise only helps to better understand things later on.
