Banjo-Kazooie: Nuts & Bolts. After having 100% on the first two on 360, it's finally time to beat this one. I must say, even though BK fans tend to diss this one, I love it. It's basically classic Banjo-Kazooie, except the transformations of old are replaced by building your own 'transformations'. The platforming element is much reduced, but that's OK. In my opinion, most of those who decry Nuts & Bolts for not being a platformer probably haven't played Banjo-Tooie. That game took the old BK platforming formula to it's ultimate extent.
Aside from the graphics, there's really nothing they could have improved. 'Tooie is massive, and the later levels are ridiculously-complex. The levels are all interconnected, and some jiggies require a lot of work. I remember one in Jolly Roger's Lagoon which requires work in three different worlds to get. Nuts & Bolts is awesome, I don't care what anyone says. Not just a great game, but a great BK game. Such immense fan-service in N&B.
Had it since launch but not actually finished it but found myself going back to it over the last few days. Love that Rare take the piss out of themselves every chance they get in that game be it comments like not having been in as many games as that plumber to loads of copies of Grabbed By The Ghoulies in the bin.
And I would have to say its one of the nicest looking games this gen and still holds up well today IMO.
I love that Rare tried something different with the series rather than just copy and past the old games into Next Gen[and hell you can buy the originals on XBLA]
And you can waste hours trying to make the perfect vehicle and some of the designs ive seen on youtube/The official site have just been amazing.
I also recommend the DLC L.O.G.'s Lost Challenges which is 400MSP.
I mean dear god, a transformer!
