Welcome,BadBud! (sounds familiar)
WFP has a bit of a learning curve, I would not recommend it as a first Patch. I wouldn't miss out on it either
WFP is an amazing UOP (UnOfficial Patch). It has over 100 planes available to fly,requires the installation of von Tom's CAMPAIGN MANAGER to switch them in and out based on game date.
CM is not just for WFP and is a good program to add to RB3D early - look into it and you'll see why.
FCJ (FullCanvas Jacket) is the most graphically updated of the UOP's, requires to be purchased.
HAG2 (Hell's Angels Gold II) is the quickest,easiest one-shot upgrade to be found for RB3D. After seeing the stock game,and loading HAG2,yer jaw will drop to the floor in amazememnt!
VISIT THE NEWBIE AND PATCH PRIMER LINKS in my sig below or YOU WILL GET INTO BIG TROUBLE!
The HA site is also a good place to learn all you need to know about modding RB3D.
Try out the game after installing each patch/program before moving on to the next.
