I usually combat the eventual boredom by having interest in a few games of differing eras at one time. I'm currently also into IL-2, as well as FS9 and EU2. Plus I think I'll look into The Sims 2. I'm not bored with RTW yet, or will I probably ever be 100% bored with it. But when my attention wavers, I'll just hop into a WW2 era dogfight. You can't take any more of a left turn than that!
