The "All American over Nijmegen" scenario in Command Ops 2 (Panther Games, published by Lock N' Load Publishing) displays the actions of the US 82nd Airborne Division in a digital recreation of command, maneuver, logistics and combat.
As for where get your bearings on the All American during Operation Market Garden, this book by R. Pouloussen is just fantastic.
What's the issue with the order to hold the heights?
After examining Field Order No.11 and Field Order No.1 of the 508 PIR, it becomes clear that "holding the Groesbeek Heights" had become dominant in the plans of the 82nd Airborne. This was not just a tactical change, but a strategic one.

What General Gaving said about this order?
"even if we were driven off the low ground, around the bridges, if the high ground could be held, ultimately the Second Army could accomplish its mission".

I played this scenario for 4 days (out of 5) of simulated operations and found myself without a feeling of being delayed or stranded at Groesbeek.
|Clearing Groesbeek with a mix of Battalions from the 508th and 505th Regiments. The US paratroopers run into trouble here and there, despite the ring of encirclement tightening on the Germans.|
|Groesbeek, finally clear! Note the clock in the bottom left window. It took almost 3 full hours to clear the stubborn German opposition.|
|If a bridge is not blown up under your feet, it is not Command Ops! A bridge goes up in the air elsewhere.|
|Around 18:00, 5 hours or so after their landing, the 2nd and 3rd Battalions of the 508th Regiment gain a foothold on Nijmegen.|
|A crucial moment of battle, day 19:35. The 2nd Battalion of the 508th holds the near side of the Waal Bridge. This had the effect of re-routing German forces via the railroad bridge on the west.|
|The Alamo at Nijmegen. One night and one full day spent kicking out the Germans who attempted to break into Nijmegen. And re-organizing my Regiments to cross the Waal ...|
|A late evening crossing by the 2nd and 3rd Battalions of the 508th. With a lot of suppression from mortars, the weary paratroopers accomplish a great feat of tactical awesomeness.|
|When the armored spear tip of the XXX Corps arrives, they shovel away any German unit that dares to sit on their path.|
The failure to make the capture of the Nijmegen Highway Bridge of primary importance produced a large delay in the advance of the ground troops to the north.

Given the differences between real life and a computer war game, and that hindsight is always 20-20, I think I can understand the issue being put forward. But as you can see, I could get away with my lack of speed and surprise to seize and hold Nijmegen. Maybe I was just lucky.
