Aside from replaying, what is WEGO except realtime with arbitrary pauses? Only being allowed to issue orders every minute is unrealistic - a gimick that allows for PBEM, and that's just about it. I don't use PBEM, nor am I interested in replaying action.
Orders-every-minute is especially painful in a modern setting - things happen so fast, you could have an entire platoon wiped out before you can even react. The bugs and quirkness associated with AI and spotting make things even worse - I tend to have to babysit most units.
There are huge expanses of time that need no pause at all, and certain cases where I need to be pausing every other second. The only flexible way to do this is with real-time pause-able. </font>
