Super Mario Galaxy: This is one example of how NOT to do a final boss.
Haha, I get it, into the lava, just like all the Bowser battles in the first game, har fucking har. I'd like to think games have evolved from that, and even Mario has too. I'm not saying the final boss needs to be painfully difficult, but challenging shouldn't be too much to ask for. Or even just something different, and not a retread of the previous battles with Bowser throughout the game. When I finished him, I was thinking "Wow, the wizards were harder than that." Then it shows the escape and the camera heads back to Bowser and I thought "Oh, it's not over yet, awesome, maybe it'll be a cool fight after all." Instead it's the Mario Galaxy equivalent of Darth Vader's "NNNOOOOOOOOOOOOOOOO!" I'm less aggravated that it wasn't challenging, as I'm probably above the intended age group for this game (though I still have a hard time with Bowser at the end of Super Mario World, as an adult) and more aggravated that I'd already done this exact battle at least twice in the game, and possibly a third I can't remember.
Overall the game was easy, aside from a couple of the late galaxies. Ah well, we got it for Julie since it seemed like a platformer more at her difficulty level, and that seems true so far. I'm probably gonna try Mario 64 at some point to see if that's any more to my liking.
