1. Difficult Combat
You aren’t a mighty hero smiting evil-doers by the dozen but a regular Joe (or Jane). You’ll be outnumbered and outgunned, so you’ll have to figure out how to even the odds, which might take a while. In the meantime, you will die a lot. If that's not your idea of having a good time, you’ll be very disappointed.
2. Requires Specialization
First-time players should NOT play a jack of all trades (aka master of none), no matter how tempting it might be when you’re creating your character. This is the fastest way to disappointment and rage-quitting. You have to specialize (combat or diplomacy) until you’re more familiar with the overall design and systems and can do more with less.
3. Gated Content
Your character’s stats, skills, and choices determine what your character can and cannot do, meaning that no matter how you develop your character, you won’t be good at everything and won't be able to do every side quest or explore every location. If this kind of thing bothers you or limits your enjoyment in any way, look for a game that’s more to your liking.

Even if everything I said sounds exactly like your kind of game, Try The Demo First. It gives you access to the first Chapter, consisting of 3 locations and about 30 quests split between mutually exclusive questlines and decisions. This way you won't have to worry about exceeding the 2-hour time limit and being unable to return the game for refund.
Should you have any questions, we’ll be more than happy to answer them.
