Nice screenshot, Widmo
@aj_: Widmo's pretty much covered it, though to add my own input: Because there are no classes it's true you'll have to spent some amount of time working towards your intended play style, but it is not nearly as extreme as Brogue in that regard.
In Cogmind floors are much larger, with a
lot more items lying around, and more importantly, you can find all the basic gear you need on the robots that use that stuff. Hunting specific bots for salvage is a useful tactic.
Another system included in Cogmind specifically to help round out a build is
fabrication, whereby you can obtain schematics to build pretty much any part you want and do that at a fabricator. Basically, if there's something you really want and cannot find, just plan to build it. (At present that is mostly a route for bots with hacking capabilities, but I'm planning to make it a little easier for non-hackers to access as well. Some players have built dozens of their own parts by the end of the game.) Fabrication isn't accessible until the mid-game, however (that said, you can get to the mid-game pretty quickly compared to the length of a full run--each floor tends to play slower than the last).
At the same time, as Widmo mentioned, even once you have your build you may have trouble maintaining it indefinitely if and when your parts are destroyed, which some potential players will find very discouraging.
