Review: The Most Excitement I've Felt in a Long Time - (This review is spoiler-free.) I found Box One when I was looking to purchase more of the Exit escape room games. I wasn't sure what to expect, since I took the advice of the first few reviews I read and didn't seek out any information about it; I've been a fan of Neil Patrick Harris for many years, and since I love puzzles and was seeking more physical games to purchase, I decided to give it a try. Box One may be a game, but it is also an experience--and one I THOROUGHLY enjoyed. I was grinning with giddiness every time I discovered something new, because it was all so clever and so... satisfying? It's hard to describe the feeling, but it's almost like the solutions to some of the puzzles were exactly what I wanted them to be, rather than what I expected them to be. There were a lot of really, really cool ideas packed into this box. I will say, though, that if you're looking for a challenge, Box One probably won't satisfy you. I'm no genius, but I never needed any hints, and never struggled on any one puzzle for more than a few minutes. Oddly enough, I didn't find this to be a downside. The puzzles don't feel like they're meant to stump you so much as they're there to guide you to the next step, and I was enjoying the feeling of being the smart person who figured it all out, haha. Just be aware that if you're experienced with escape room style games (or similar genres) this will feel pretty easy to you. And again, if you're at all experienced with puzzle games, Box One probably won't take you very long to finish. I went at a leisurely pace and still finished in maybe 3 hours split between two days. Nothing gets destroyed along the way, so you can technically replay it, but you'll probably want to wait a few years so everything is a surprise again. I still think it's worth the price for how much fun I had, but if you're on a tight budget and need the most bang for your buck, there are plenty of other board games or video games that will give you more playtime. Overall, I can tell that a LOT of time, effort, and passion went into designing Box One. I can't remember the last time I felt so much child-like excitement, and in this day and age, that kind of experience is priceless. I have already purchased Box Two and look forward to seeing what new surprises it brings!
