I grew up in the Marvel Handbook years, so I like some deets on what the characters can do, instead of marketing slogans like 'god of cities.' I definitely wanted an idea of what the Engineer could do with 'ten pints of nanomachines for blood' since she *seemed* to be able to create tech that was a heck of a lot bigger and heavier than 'ten pints' of anything (was her nano-blood swooping out and appropriating and reassembling other nearby matter to build her constructs? Cause that would have been cool to know, and see, a nearby car just seeming to rust away as it's metal is eaten up and used to form whatever she's making.)... She wasn't a tenth as 'pull new powers out of my butt' as the magician character, but still, I like a little more science in my science characters, yanno? Let's get technical, if we're building a techie! (Due to the nature of her powers, I always thought she'd be the best for a solo arc, actually.)
There were a lot of great '80's action movie' feeling scenes where Arnold makes the quip before dropping the grenade or whatever (and I felt like this was a feature of this era, comics that felt like action movies), but I would have liked more of a sense of a 'story bible' existing behind the scenes, not one that *I* could read, necessarily, but one that the writers could consult so that I'd at least have the illusion that *they* have some idea what these characters can do, and that *they* know a little bit about what makes them individuals and not just differently-shaped and colored iterations of 'quippy badass.'
