It's also about having a nice progression and variety in the gameplay. Like the mark and execute. I mean, we could make an entire level that's very easy. One guy who's not looking at you, you kill, you gain the execute, two other guys not looking at you, mark mark, you kill them. The whole game could be like that. But then as you go maybe there's gonna be three guys and you only have two marks but there's an explosive barrel. So you can really build a nice progression.
The player learns, and feels smart - because it's a Tom Clancy game and they need to think.
