Firewatch is a single-player first-person mystery set in the Wyoming wilderness, where your only emotional lifeline is the person on the other end of a handheld radio.

The game would have been MUCH more entertaining if it was actually based only on your job as a member of the firewatch, but no, they had to make an actual story and focus on the narative part of things, which makes the game much more bland and boring. Other than the sceneries and maybe a some of the dialogue (the voice acting is brilliant and the way it all looks is sometimes amazing) there really isn't much to enjoy in this hiking simulator. In fact, the message barely gets into your head if you pay more attention to the gameplay faults it has. I only played it once and didn't try to find the whole meaning of it, but I still enjoyed the first hour of the 3 and a half it took me to complete (hike through) it. The ending really isn't awarding at all, it leaves you with questions that won't be answered (i hope there won't be sequels) and in both cases it is utterly anticlimactic.
End of review: 7.1/10. I've seen way worse, it deserves that much, being made in Unity of all engines and still looking like that is amazing.

I really enjoy narratives to be honest. and Unity 5 is a pretty versatile engine for weak PC's.

It is indeed a good engine for weaker PC's. And I only stated my personal opinion, never said it's a bad game, just not one that focuses on the gameplay. And I don't say a game should have unbelievable gameplay to be enjoyable, it is just that the story had so many irrelevant factors to the main plot and the ending was so unsatisfactory, that I felt like I didn't do anything in the end. Though I still completed it and somewhat enjoyed the dialogues and a big part of the story.
