Must have add-on's for FS2004?

>Just wondering what some people consider must have add-ons>for FS2004? things maybe like Active Camera, Active Sky,>differnet aircraft, etc... I like flying C-172 for real world>practice, but haven't found a really good one yet with a>really nice VC that everything works in..>If you haven't already got it, your first purchase should be the registered payware version of FSUIPC. It's the building block upon which so many other payware addons rest.After that, my two serious must-haves would be FSNavigator and ActiveSky 6. FSNav is great for navigation and flight planning, and AS6 is the best weather program ever for FS.Then check out the Flight One C172 and see what you think.Lewis "Moose" GregoryRichmond, Virginia
