I didn't mean any offense to anyone that uses Godmode at all. Just ruins it for me personally. I understand having limitations, believe me. I severed a tendon in my hand a few years ago and my left thumb can not give the "thumbs up" it just stays to the side or goes forward. Additionally, I have a very hard time playing on a standard keyboard. I think I am getting used to this new Razer gaming key pad thing but it really hurts and I have to play in short sessions.
For me, it's not so much that being invincible or having a ton of weapons and ammo, it's being able to watch the enemies A.I. and seeing how stupid they really are. Kinda like when you learn how to clip on older games by peaking around the corner. That's all. That's why new games are so much fun for me, to see if an enemy will search or change tactics or something.
