So, you know, the whole Call of Duty and Battlefield thing has rolled around again, and I'm expecting them to be absolutely no bloody challenge whatsoever. Just the other day, I bought Half-Life 2 off of Steam, having never played it before (shock, horror, etc.), and I was astounded to find that the game proved quite a challenge on harder difficulties, mostly because I was constantly being hammered down to 3 HP within minutes of every stage and had to go around saving the game after every wave of enemies I survived. I probably had the most fun with Half-Life 2 since the mid 2000's, mostly because it was really damn hard. I know this has probably been asked a billion times on The Escapist forums, but do you guys prefer Regenerating or Non-Regenerating health?
