Star Wars: Shadows of the Empire (N64 - 1996)

Then:
Powerful new system, epic soundtrack, unbelievable graphics and varied gameplay. The first level (Snowspeeder vs. AT-AT's) was a window into the future of 3D (everyone was done with 2D by then). Goodbye SNES!

Now:
An unplayable, glitchy, cheap, blurry mess with terrible controls and one of the worst 3D camera's of all time.
