I've chopped and changed all kinds lately but this is good, purely because you can be a complete idiot on it and kill in the stupidest ways possible

It's still nails hard IF you want it to be, I'm playing on normal though and it's great fun

I never really stuck with the series, I remember playing the first couple and overall finding it too difficult (hard as/harder than Thief?) and gave up on it, but I know I found Thief a more enjoyable experience. I think I'm just not a stealth person, I'd always rather go in guns blazing and sod the tippy-toeing and skulking in shadows.
