I think the /idgames web front-end rating number itself is completely useless and should be done away with. The comments have the potential to be much more useful, both to the author and potential players. But the rating number (and thus average score) is meaninginless since everyone rates things with different criteria, weights and expectations. For instance, I wouldn't be at all surprised to find some trollwads with higher score than this or other "serious" PWADs that the authors have put significant and honest work into. So then this begs the question: why even bother making real maps to begin with, when it's much less work to throw some halfass shit together? At least then you won't feel so bad when some trolls just wanna have fun or some angry player decides to vent. Ultimately the only real, valid reason to map is because you find it fulfilling, because you enjoy it. And in that case, the score is irrelevant! Feedback is important, because it can reveal some bugs, weaknesses or problems (that you may or may not wish to address) but there need not be some number attached to them. This rating mentality that you see everywhere these days (in one form or another, like +1, or up/down voting, etc.) is completely retarded! It encourages an externally-motivated mindset, where your self-worth is determined by others - see John Gatto's lesson 5. The quicker you excise this mental ball & chain that is implanted from an early age, then quicker you can find your way to real fulfillment. And that path may well not be identical to everyone else's. It would be a very boring world if everyone enjoyed the same games, same style DOOM maps, etc. Bottom line: you're making a HUGE mistake if you give this nonsensical score any credence, and if you map for others instead of for how you feel inside. This is pure art, not a job where you have to perform according to some business needs. Let's not have any of that bullshit here. This is a hobby, and a place to have fun and relax.
As far as the PWAD is concerned (Castle Doom), I checked it out because the idea sounded cool (I'm a sucker for medieval style maps). Unlike others, I really liked the "big" architecture and sparse level of detail. It reminded me of Michael Krause maps (runbuddy.wad, moon2000.wad, time2die.wad, etc.) but the gameplay isn't nearly as hectic (I only made it to MAP03 so far though). Didn't notice any big problems, other than HOM around the fireplace on MAP02 (using lastest PrBoom+). I got stuck until I figured out what the red marker stones were for (maybe some kind of medievalized "switch" graphic would have worked better).
You get where I'm coming from on the work you put into something and then to see it trashed when someone probably only loaded one or two maps up. It's a bit discouraging.
On the plus side, I do understand what people like nowadays, and I know what I did wrong...I just wish I didn't devote 4 months straight before getting feedback. My bad.
