Eh I think you're hitting the whole "people hate me because I think different" drum a bit too hard Prez and I don't think it really applies here. Most people have given you rational explanations why they think X health system is good rooted in gameplay mechanics instead of simply falling back to personal preference or subjective enjoyment.
I think there is a place for both but I also think health items (should) apply to a much larger percentage of them and that regenerating health gets forced into many games instead. The reasons why have already been covered in detail so *shrug*.
L4D Expert would like to have a word with your lack of tension. Talk about a game where regenerating health would clearly ruin the atmosphere entirely... I don't think it's a situation where it's "ruining tension" but not creating any "tension" at all in the first place.
Indeed, a great example. L4D Expert is about as tense as it gets and regenerating health would ruin that experience. That's not to say that there isn't a place for both ease and tension but its alot harder to create tension with regen systems.
