Totally. Being stealthy gets much easier as you unlock more/better equipment. And you'll get buddies besides the horse that will make your life a whole lot easier. Not to mention how much easier reflex mode makes everything. There were a bunch of times where I just walked right up to a gaurd, entered slow mo cuz he saw me, head-shotted him with my tranq gun, then walked up to the next nearest guard and did the same thing. I've never cared about trying to get S rank or no detection and all that, but after awhile I found myself getting it by accident.
