I'm very late to the party on this one, so let's have some context. While I haven't written about it regularly for a long time, I remain a huge fan of The Mecha Hack. The reasons for this should be fairly obvious. I've previously backed one Kickstarter for the system, and when I heard Absolute Tabletop was doing another, I'd backed it on principle. It was a fantasy game, not my usual vibe, but they had built up a lot of good will with me, so I went for it. The Kickstarter was funded, which was followed by a lengthy wait, and eventually, my preferred softback edition. I'd had an earlier pdf, of course, but I'm wedded to the dead tree format. So, much later, I had a few train journeys and decided to do a brief write-up.
Let's address the matters of rules and theming. Aether Nexus is a spin-off of The Mecha Hack, itself a variation on The Black Hack. As the word "Hack" implies, this was originally a minimalist ruleset, so minimalist I will admit to not quite getting it at first. Aether Nexus, coming after the Mecha Manual expansion has drifted away from that a bit. I've handled much more confused or bloated systems, Call of Cuthulu or the Power Rangers RPG for example, but this game trades simplicity for character. It's not a generic system this time, it's strongly themed with it's own character, forming part of the somewhat niche fantasy mecha subgenre. Think Escaflowne, Magic Knight Rayearth, and more recently Knights & Magic. An initial annoyance I had here was the tendency for every rules concept to have it's own, reskinned term, this being a game that includes a glossary. Had the setting hued a bit closer to the D&D template, this might not have been an issue, but there's clearly a bit of front loading required. Also, as the game doesn't feature the Tolkien standard fantasy races, I foresee issues sourcing reference images and the like, but your mileage may vary with that one. Don’t use AI.
Mechanically, the game replaces a few rules with more interesting ones. Degrading dice mechanics now trigger on a 1 and the maximum, with that maximum triggering a special ability. Armour now uses such a mechanic, no longer functioning as an expendable HP alternative. Melee and Ranged attacks now key off different stats, while the weapon types have been dramatically expanded. Character progression and money have effectively been rolled into one, with Arsenal points being used to get new skills, stat increases, weapons, and so on. Another thing you can spend Arsenal points on is the party sky ship, which is very much a character in it's own right. I was quite impressed by the chapter, and can see this being transferable to other genres fairly easily. Throughout the above is a big focus on teamwork, with a majority of abilities that benefit the party rather than yourself. This ties into a wider theme of players being magically bonded, also serving as an in-universe justification for magic radios and OOC knowledge. All in all, it seems a complete ruleset that's built on previous successes, although I'm not sure how the game balance will look. I've not had opportunity to actually play this.
I suppose the greatest strength, and weakness, of Aether Nexus is it's theming. As a rulebook, it's consistently gorgeous and well-presented. I love the art in this. I also like the extensive selection of GM tools and charts. Both are vital for building the world Absolute TableTop had committed to. But, there also is a weakness. Magical mecha is a niche within a niche, and they haven't taken the easy route. I don't know if Aether Nexus would have been a better game if it had been more D&D. I'd want to run a campaign before making that call, but I suspect that it may have been more accessible. I would have liked to build on this book, instead I have to work within it's rails, or gut the rules and start again. And I'm confident I could have done that with The Mecha Hack… But then again, I'm a weirdo whom makes homebrew for fun.
I'd sum it up like this. If you like the look of Aether Nexus, and it is very pretty, go for it. It's a complete and well-presented system, that's good at what it's choosing to do. It you're looking for a more generic or sci-fi system though, look up The Mecha Hack instead.
