Currently playing Deus Ex: Human Revolution. I really like it, if it weren't for those fucking boss fights. I mean, they're probably not that bad if your usual MO is to just fuck everything up. But I've been playing towards the Pacifist Achievement, so that means a lot of sneaking around, a lot of non-lethal weapons... all of which is worthless against the bosses.
I find this really annoying, to be honest. It's like "Play like you want! Kill people, or don't... but here we're going to punish you massively with sections that completely break the flow of the game if you played without killing other people". Sure, there's weapons there and stuff, but none of my augs are geared towards combat at all, and I just end up getting shafted.
I'll try again tomorrow, but so far, these boss fights (currently on the second one - the first one was annoying as well, but it was doable because of the shitload of explosive barrels standing around) have been a real blemish on what otherwise has been an excellent gaming experience.
