Twilight princess's Graphics are on top of most of these games out there, not just graphics,level design,animations,etc.
Not to mention it has solid gameplay...but enough of that and let me get back on topic.
I bought Banjo-Kazooie(N&B) when it came out and it didn't disappoint me at all.
I hear many people giving it bad rep. because it didn't stick to the old formula but if it stood the same way they would give it bad rep. for staying the same.
I like the fact that it cost only $39.99 new(At least where I live) which it's about #30 less than any new game...and let me tell you that the price should rise seeing as this is one of the best platform-Misc adventure games this month and probably this year.
May not have the old platform formula but it's a fun game never the less, creating vehicles gives you a lot of options and puts your creativity to the test.
Just give it a try, you can even download the demo before buying it.
