I played Just Cause 2 for a few hours before I dropped it. It's what I call a GTA clone. Lots of running around blowing stuff up but never really DOING anything. Just not fun for more than a little while for me. As such I'll avoid Just Cause 3. I hope Hitman isn't like that.
Actually JC has always been as much if not more so about the stunts than it is the demolition. Case in point, a lot of people agree that GTA V's story, characters and dialog get a bit over the top with in fighting, leaving most to horse around when bored. JC are games you can do tons of horsing around in.
And quite honestly, if you're put off by the repetition in JC, there is just as much in the new Hitman. Content isn't exactly it's forte. You only have two difficulty modes, Normal and Professional. In Normal mode there are several "Opportunities" (methods of dispatching the targets), but you are still playing through the same map and there are Intel objective markers that literally lead you the whole way.
The only way to play Hitman 2016 is on Professional, but even then, once you know how each Opportunity is set up, they don't take very long to achieve. It's a game with only a handful of locations and only 2 or 3 missions in each one. The game is well optimized and looks great, but honestly, I had more fun with Absolution, and it's combat works better too. In Hitman 2016 you'll want to play it almost entirely with stealth, esp on Pro mode.
People can say what they want about Absolution's same uniform NPCs spotting you too easily, and the arcade mark and execute feature, but the same uni awareness is still there with NPCs that are in paths of infil or exfil, and the mark and execute worked well to add to challenges and extend replay value.
Basically everything that people complained about with Abs is still here, it's just that maps are bigger, but content is way smaller. I don't know about you, but I don't think having to play the same missions over and over with different kill methods is as good as having a nice long campaign.
