And, in almost all cases, don't throw out things because they are "too screwy." Almost anything can be worked into an encounter or campaign.

(Just wait to see the players' faces when a bunch of guys wielding halberds jumps them in the forest...)

And don't throw out your D&D stuff or other such things. They are a treasure trove of maps, and the NPCs can be changed to something more modern. (Dungeons make great maps for underground communities, coal mines, hidden weapon factories, etc.)
