I was a huge Rare fan back in the N64 days. Banjo-Kazooie, Banjo-Tooie, Conker, Perfect Dark, 007, Diddy Kong Racing, Jet Force Gemini, Blast Corps, and Donkey Kong 64 are all part of my collection. There was a time I would have put them right up there with Nintendo as far as making entertaining games. When it became evident they were moving to the X-Box I was very disappointed.
However, to be honest, they have yet to show anything since then that has me wishing they were still with Nintendo. I did buy Star Fox Adventures for the Cube, their last Nintendo game. I'd rate it nothing better than average. It had some nice features but I didn't feel they all came together to make the game fun. I have paid attention to what they are doing on X-Box and from what I have read, it hasn't been much. They've only released one game in about the last 3 years (Star Fox) and most of their other projects are away off. Every E3 report I have read said all of their games were disappointing. Perfect Dark is still years away from the way it looks. The others just weren't that fun.
I don't miss Rare nearly as much as I thought I would but that tends to happen when the Cube still has more Rare games out than the X-Box. Maybe I'll be jealous later but I doubt it.
I will be very interested in their GBA games....if they ever release them.
