How long do you think Microsoft will keep them before they eventually get booted if that even happens? I just see it as a developer that they will milk to death but I'm not overly sure what will happen in the end. My biggest issue with Microsoft owning them is how many great IP's they have but they've practically lost/fired many of the original workers who were part of teams that created games during Rareware's golden era. I honestly wish that they would use them as long as they wish just so they give them the boot eventually, there hasn't even been a good game from them since Viva Pinata.
EDIT: Nuts N Bolts wasn't that bad of a game but it wasn't for Banjo, the game even felt stellar enough for platforming and as JonTron even said, the game feels like it was originally (early) a platformer, just go to the tower in the middle of Showdown town and do the platforming segment, it's pretty decent and it played well. I can't also help but notice the amount of sarcasm regarding platforming in that game, it's also as if some of the devs for the game wanted it to be one but Microsoft and the Stamper bro's said otherwise.
