Haven't played any more today, no.
I have put together 4 'coup de main' variants, in fact (because I too loved that [and other] alternatives in the original HTTR), and played them a bit too. Much easier to win. In one I made a new airdrop SEP, in the polder near Elden. That way it's quite easy to stem the flow of armour at Arnhem, and hold until relieved. If you keep only the original SEP, miles away, then it becomes a very interesting fight. Not certain either way, because even though you can stem the flow initially, you very quickly lose supply. Question is then whether you can get XXX Corps across in time. From playing through many variants of the Nijmegan, Arnhem Operation - if this game is really worth anything in terms of history - I'm convinced that the Operation would have been winnable (if very costly) if they had had shorter lines of supply, if they'd somehow managed to drop supplies into Osterbeek, for example (as they did, with poor accuracy) in greater quantity, or if they had set up a drop zone for supply in one of the many possible areas sth of Nijmegan, but much closer in than the actual drop zones. Even dropping the troops so far out I think they could have then got to Arnhem in time. Because the map has crucial choke points the overwhelming strength of the Axis is not so great an issue, even on the number of divisions they put in. But keeping those divisions in supply is a nightmare, especially at Arnhem. Just not enough men to maintain such a huge cordon.
