Definately more but American football is a very different game than soccer, hockey or basketball which are continuous flow games. The play is over when the ball/ball carrier is down. The other games the play is only over when the ball/puck goes out of bounds. Comparing apples and watermellons.
You seem to have a sensible approach, more so than many sports fans who are fanatical protective of "their" game.
I love American Football, but it is a different game than real football. Real football will always be closest to my heart as it is the game I grew up with.
Which game is better is pointless to dicuss.
To quote James Bond:
[James is in bed with a Ling, a Chinese woman]
James Bond: Why do Chinese girls taste different from all other girls?
Ling: You think we better, huh?
James Bond: No, just different. Like Peking Duck is different from Russian Caviar. But I love them both.
Cheers.
