Not to be the pessimist here, but the first thing that came to mind when I read this is 'if this game were on a console being reviewed, the review would be mostly negative with the main argument being 'it's been done over 100+ times better before' and start comparing it to better games or games that it resembles. However, I'm guessing it is being viewed from the 'gosh I can't believe this is done on an iPad/iPod' perspective so it escapes being scrutinized.
I'm not bashing the game because it does seem to be an interesting game nor am I troll attacking this review or the reviewer; Mr. Pitts' reviews are cool. My point is that I've started noticing an opinion pattern with games released on major consoles vs games released *currently* non-mainstream device. If it's a game with common mechanics on a device and as long as it plays decently, it's considered a great game. Take the same game and put it on a console, it then becomes boring and lame.
I have a theory: take Afro Samurai the game. I thought it was decent but the problem is that its mechanics were dated. If it was released on the PS2 in its mid-season or before action games like God of War, it would have been received well. Now let's say it was not released on a major console. Let's say instead, it is about to be released soon on the iPad as gaming attention and potential are growing for it. Do you see where I'm going with this?
