Yeah, the price is fucking steep. That was the last game I'm investing in for a while, but at least the price won't be changing once the actual game comes out.
It's a fun game. I die too much though. It pisses me off.
I think it can work on most PCs. Firstly, because I actually play DayZ on my Mac (using a Windows boot), so if my Mac can handle it... Also because one of my friends that plays it on a shitty PC managed to find some sort of workaround in the config files which makes it run perfectly (albeit with low graphics).
I really want to try it out but the price is a bit steep and I know my POS computer won't run it very well
If you like the Walking Dead, then this is the closest gaming experience you'll have to a Walking Dead game. Once the full release is out, they'll have stuff like building your own bases and shit, so you can pretty much take a town and make it your own Woodbury.
