So coming into from the perspective of one who doesn't play wargames myself, I really can't think of any inherent flaws with either the concept or the mechanics. Lighter frames move faster but heavier units can carry more equipment to attack with. certain abilities generate heat which gives you more abilities depending on your equipment at the cost of reducing your character's dice pool for the turn, different weapons hit on different values that you roll on the dice, it's all pretty straight-forward, even for those who aren't very familiar with wargames as a concept.
The visuals of the game were a bit choppy admittedly, with some entries on the equipment page missing spaces or having a handful of typos and some sentences really needed to be turned into a new line since it caused some entries to read like a literal block of text that make it hard to read at times, especially when all the text is centered on top of everything else.
Overall though, it's a pretty good game. While I cannot recommend to any one particular group due to my own inexperience with wargames, I can at least recommend that those of you who are looking for something to introduce themselves to the hobby with, this game is a good place to start, even if it is a tad rough around the edges in some regards.
