I personally enjoy flying DCS and reading a good book at the same time.
1) Pick plane you like
2) Slap on fuel-tanks and fill her up
3) set weather to worst conditions imaginable (night, stormy, no moon)
4) take off using instruments only
5) set course for some distant airport
6) try to get above the clouds with maximum fuel load
7) read book while listening to engine noise, occasionally correct course
8) set up instruments for instrument only landing
9) contact ATC
10) attempt to land
