head to head
Tom Clancy's Ghost Recon Advanced Warfighter asks more than Command & Conquer: Renegade, and the gap is optimization.

Execution · Practiced Mastery
FPS aim welded to a team economy of base-destruction priorities.

Execution · Practiced Mastery
Planning approaches with recon tools, then executing them under lethal fire.
Command & Conquer: Renegade leans Execution (Practiced Mastery); Tom Clancy's Ghost Recon Advanced Warfighter leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Command & Conquer: Renegade
FPS aim in infantry and vehicle fights carries the game
Tom Clancy's Ghost Recon Advanced Warfighter
Lethal firefights punish sloppy aim and exposure
Tom Clancy's Ghost Recon Advanced Warfighter leans a little harder on reads, though the gap is small.
Command & Conquer: Renegade
Multiplayer base assaults involve predicting human team pushes
Tom Clancy's Ghost Recon Advanced Warfighter
Multiplayer squads outflank and adapt to your habits
Tom Clancy's Ghost Recon Advanced Warfighter leans a little harder on variance, though the gap is small.
Command & Conquer: Renegade
Maps and economy rules are fully known
Tom Clancy's Ghost Recon Advanced Warfighter
Enemy placements are scripted-but-unknown on first attempt
Tom Clancy's Ghost Recon Advanced Warfighter leans clearly harder on optimization.
Command & Conquer: Renegade
Credit economy and building-target priority decide C&C-mode matches
Tom Clancy's Ghost Recon Advanced Warfighter
Drone recon, squad orders and approach planning decide missions
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
