Yup, Glide gave birth to the 3d industry. 3dfx is now abandoning it and if anyone cared to look, they'd see that the 5500 runs D3D better than Glide, it's not a one API card. In fact, it supports more useful API's than any other card. Some games certainly still are better in Glide, but that's not 3dfx's fault. If Glide hadn't existed many of the games we play may not even exist.
