He's a generally fair reviewer. Not surprisingly, he makes strong references to Smash Bros., but seems to be among the fairest in how they effect his view of the game. Though, they may be excessive to a point. Think of it what you will. I've been a regular watcher of his videos for a while and I think he's a good reviewer in general with his own rating system.
I follow Jeremy Jahns as well, and he is a pretty good reviewer. I agree with his point that if you want to get the most for your money, you should have a Vita, the whole cross-buy thing is just great. Hopefully Superbot learns from this game and improves on the next game, like he said, the whole game almost looks like an experiment of sorts similar to the original Smash Bros (which only had 10 characters and 7 stages).
Jeremy Jahns is awesome. But one good look at his comment section and I always want to blow chunks. Seriously, what a bunch of brats.
Now that I look at it, they do seem more along that line, lol. Never really paid that much attention to that before.
