I don't think I ever saw how you can place ships and stations, so quick battle was pointlessly dumb, just ships flying at each other, circling and shooting.
There is something to be said for that style gaming though. We got into Tiger Woods lately with the Masters going on. A nice contrast from the intensity of deeper games. I too just don't have time or sustained interest in most games. I did finish far cry 3, first one I've played through in years - largely due to a decent autosave.
I've never finished a GTA game due to the same problem.
