Heh-heh-heh, it's strange that you didn't know! There's a great program about all the heroes (it shows all the information about them!). You should study that, and the "digging" is just...:smile01:
Sincerely, VDV_forever
The only thing I agree with you on is that all this "digging," load/saving, and replaying turns is tedious and uninteresting, but it can greatly affect the result in offline play. On this map, I replayed it several times, and I only rewound by one day at most. I replayed battles for a long time, which is also not ideal, but it's more interesting than repeatedly using load/save to "dig" something up.
But after scouting the map and if I know exactly who I will especially need, and this will greatly reduce the time it takes to complete the game, then yes, I might spend a couple of days "digging" :) The problem is that I didn't know that :) Grab the "sledgehammer meter" and go for it – that's roughly the tactic I used for my first two weeks
