Hmm... Saw the Echoes from a friend's book. Not super happy with the limited number. MMRI is totally redundant isn't it? And Skinlink being an echo means every TM has their first 13 Karma predetermined, realistically. And kinda annoyed by the FFF echo since it makes actually having built a TM character to use a Pain Editor be... Pointless and less unique. And Mathemagics? Really? A +2 Limit to a small group of rolls? A static limit increase? This should not be an echo. This should be a quality like Analytical Mind. Quiet and Resonance Scream are interesting and kinda useful at least, though again it bothers me that it's a static number. A number literally every decker can easily beat, but... Whatever. Two is better than nothing.
I just have to say... Like, cool, awesome. TMs are gonna get their own book. But god dammit, to be waiting for Data Trails since the edition came out to see TMs get a bunch of material, only to hear like freaking week before it comes out that "Oh, no, we're saving all the good TM stuff for a book you have to wait even longer for!" pisses me off.
I'll probably get my own copy but... I'm disappointed. Not even streams and paragons! I mean, seriously? This would be like if fucking Street Grimoire came out three months later than it did, but it lacked anything about mentor spirits and traditions, had half as many spells and half as many metamagics. And then someone came and implied maybe those things would be in the next book specially for magicians that you'd have to wait three more months for and pay for as well.
I'm not saying this is some kind of marketing manipulation thing, but I'm not comfortable with how close it gets to being one by coincidence. This is a serious disappointment.
I really hope the TM-specific book actually does what it needs to, so the people who write it don't get threatening emails from twice-burnt fans.
