I distinctly remember "Redneck Rampage" being the first game I'd ever played with an install over 100MB and it blew me away - that felt absolutely MASSIVE at the time.
The physics engine in "Jurassic Park: Trespasser" also knocked my socks off. I wish that one would get a re-release on GOG or something; it's terrible, but I've got a lot of fond memories bumbling my away around that island.
This is seriously one of my most anticipated movies. "Black Dynamite" is an absolute comedy masterpiece.
