Ninja Trek is a more mainstream-style RPG than Hypercronius. What I mean by that is that it is a little longer, has more combat, and less dialogue. It also has a slightly smaller price tag (It's hard to get smaller than that of Hypercronius), at a mere .012 BTC. I'm going to try and review Ninja Trek by it's own merits, rather than comparing it to Hypercronius, but we'll see how successful I am in that regard.
There are, like in Hypercronius, a lot of obvious and not-so-obvious references to esoteric ideologies, which add to the richness and apparent depth of the environments in the game. One can't miss the use of the Ankh and the Garden of E.DIN, for example.
The Message: Where Hypercronius is very, very story-heavy, Ninja Trek is a little more gameplay-driven. As such the message is mostly contained in they payout at the end of the game ("Kami do not kill!"). The protagonist/player is faced with what could be called a moral dilemma which has profound implications in the world laid out by the game's plot. If one is inclined to meditate on the story and the ending, they can easily tease out different implications concerning the nature of power, domination structures, and even the NAP.
A little bit of meta-game message is bundled in as well: the game's EULA is actually the BipCot license. It is pretty much the only EULA that I recommend anyone read, as it's the first ever license that I know of which is valid under the rubric of the NAP.
The Rub: If one is expecting the level of text, story, character development, and drama experienced in Hypercronius, they will likely be disappointed. In addition to being less dialogue-driven, there was a noticeable absence of voice acting and sexy sprite-humping. However, the game stands very well on it's own as a classic RPG-style hack-and-slash. I encountered one bug towards the end of the game that led to the game crashing, but I was unable to recreate the bug (it's just as likely my antivirus breaking things as it is a flaw in the actual game). Fortunately, the age-old "RPG best practices" of saving constantly meant that I only lost about 5 minutes of gameplay to the crash.
The Verdict: For just a few dollars, it's hard to go wrong. Again, Zomia Offline Games successfully delivers on the stated goals of their project. Ninja Trek is an excellent companion piece to Hypercronius in that they compliment each other's absences. Where Hypercronius lacks the more traditional hack-and-slash RPG elements, Ninja Trek has it in spades; where Ninja Trek lacks full-motion video, voice acting, and visual-novel levels of dialogue, Hypercronius has more than enough. Seeing as how one could get both for under $10, one can get the full anarchist 16-bit experience for the cost of a cheeseburger.
In it's own right, though, Ninja Trek is well worth the couple dollars for a couple hours of nostalgic adventure true to the medium which simply doesn't exist in the modern gaming landscape. The anarchy just makes it that much more fun.
Oh, and you can buy it with Bitcoin in addition to the usual PayPal et al.
TL;DR: 4 out of 5 stars, fun game, good combat engine, fun environments, yay anarchy. I'm certainly looking forward to Hypercronius II as I've come to expect great things from Zomia Offline Games.
