... also the general gameplay is pretty hella' different insofar as 2D fighty-platformer goes, from what I've seen. DC's a lot, uh. Faster? Than S&S. I guess it'd be something like comparing... gods, I don't know, it's been probably over a decade since I've played a 3D brawler. Devil May Cry number whatever? With something from the souls franchise. They both share some persistence mechanics and some themes gameplay wise (dodgybits, mostly) with Souls games, but DC is very much not a souls style game in terms of pacing and whatnot, whereas S&S is notably closer to one. There's a lot more than one major difference, heh.
Any case, the time vs. money thing tends to be a matter of flexibility, for lack of a better word, for me. There's points during the day you have a great deal of difficulty expending time to obtain food, which can easily be spent on free!game instead. Can make free worth time whereas even a dollar wouldn't be if for some ungodly reason you're actually trying to hardcore minmax your gaming time.
No matter how much some people like to babble about time equaling money, not all time is made equal from the standpoint of time to money efficiency, which can distort how much a price tag influences your (lack of) spending habits. Also there's totally a whole pile of other shit to deal with spending money online you can just not with free stuff! Other considerations, too. Lots of little variables and junk, basically.
... also while you can't get rid of it (actually, I'd wager non-existent money you could contact steam support and ask them to get the thing out of your library outright, though a refund almost certainly wouldn't be involved), you totally can hide games you don't want to see in your library on at least steam, and probably other platforms. Though I forget the exact button pressy things at the mo'.
