47 gets a police disguise -> every policeman on the whole level detects him almost instantly, which implies that every policeman knows the face of every other policeman and is able to detect a "new" face in an instant
47 gets a SWAT disguise, that even covers the whole head -> every SWAT member on the whole level detects him almost instanly
It just gets even worse for the higher difficulties. Because on those, any policeman from 100m away can detect you - which again doesn't make any sense.
And even if we accept that as "making sense" - why is everything else too much for the AI? I grab a Special Op member right after him talking with a buddy - over a table - and the other member even looks back and doesn't think it's suspicious that his buddy just disappeared within a second?
most stealth games, and certainly most hitman games are full of situations like that.
apart from that, I think the new disguise system was a welcome change, the mechanic that all guys with the same costume recognise you faster than others makes generally sense, but yes, of course there are many situations where they dont make sense at all, as you pointed out. but again, past hitman games had countless situations, too where diguises didnt make sense. in blood money they were brokenly overpowered and it didnt make sense at all either ind many situations, nobody complained there.
the problem is not that its "unrealistic", hitman never was realistic and doesnt need to be, the problem is that the mechanic changed, it became harder and less forgiving, and many people didnt like that, I did.
still, absolution is not the best hitman game, it doesnt come close to the series best (contracts and blood money) and has many flaws, mostly the too small and too linear level design. but its still a hitman game, and not a terrible one.
what most people seem to forget, there are more hitman games than blood money, and most of them felt very different. the disguise system always changed a lot, and hitman 2 for instance was very linear and story oriented, too, and its actually the fan favourite and the one that sold the most, behind absolution.
as a fan of blood money, I dont like it either that IO took a step back towards hitman 2 with the linearity and story focus, but I cant really blame them either when you look at sales and polls in their forum (where hitman 2 was always number 1).
I didnt play splinter cell conviction, but I still dont see absolution as a usual stealth game, I played it exactly like very hitman game before. which means 1. exploration 2. find a plan 3. execute that plan flawlessly. all of this with countless trial & error.
as I said I didnt play splinter cell conviction, but I cant imagine it plays like this, otherwise I may have to pick it up.
absolution is a good game, and a true hitman game, but sadly only a decent one. its simply nowhere near blood money. but thats not a reason to kill tha franchise, I think it could have been easily saved. absolution has also brought many improvments to the franchise that I need to see in future installments.
