Banjo Kazooie was an immense game developed by Rareware in 1998. It had a sequel, Banjo Tooie, in 2000.

Both these games were absolutely amazing. Tooie especially. It had the best graphics for the N64 (besides conkers bad fur day) and had links between levels hidden in levels. It was brilliant.

I still have these games, and I still play them.

Anybody else?
