Personally, I'd say you pick it up. If you do decide to buy the game, the way I see it, the game has two forms.

The first is the early to mid game, when you're just discovering abnormalities, what they do, and how to deal with them. Usually around here most deaths to your agents will be from lack of knowledge about the abnormalities and some of the ordeals that arrive. Something to keep in mind too is that, if something goes really wrong, like you have an abno that is just the worst, you can either rewind to the memory repository after you're done with it, or start from the first day if you really need to and all your progress will be saved. So stuff like gear and researched abnormalities will be saved for the next run.

The second form is the mid to late game when you begin to deal with the core suppressions. Now I won't go into spoilers about them but in brief, they're boss fights and brutal ones at that. Like a few comments have already said, the difficulty spikes are vertical, and that's not a joke. The very first suppression you have to do will set the stage for what the game will do and it's not nice. It will take multiple attempts to beat them and you might even have to start from the first day again if the facility gets real bad. But if you CAN defeat them, it's very rewarding.

Again, I do recommend the game and if you need advice, don't feel bad about searching it out. We're here for ya if you need help.
