I was planning on entering the contest before I read the rules, but now I just don't know.
Here are my thoughts...
First, the "new" gametype to me personally doesn't sound very interesting or fun. Basically making an instant capping CP map that relies on a single person making the cap rather than a team effort seems like it would have some pretty big problems with the inherent gameplay.
Second, pipleline has so far been incredibly spammy and unfun for me. This may just be because of the map itself and not the game type, which would mean an infusion of different plr maps would be great. If I do enter the contest, it'd be with a plr map, but I'm still unsure if the gametype can be as fun as pl, cp, or ctf.
Third, the judging criteria seems fairly counterproductive in my opinion. A map should be judged on 2 main things, fun (gameplay) and aesthetics - with fun being weighted significantly more IMO. Now, you can break that down however you'd like and fun would incorporate balance and gameflow and aesthetics would incorporate detailing and style, but the "fun factor" isn't really represented in the criteria. Seems like a person should be able to go say map A is better than map B, but with the current criteria, B may easily end up with more points even if everybody thinks A is a much better map.
I suspect people will look at the points they give in each category and then artificially "fudge" them to make sure map B ends up with less points than map A, but at that point, the categories are purely an obstacle that people would be ignoring anyway. A person shouldn't have to think about exactly how a map is better in whatever categories, they should be able to just say they like one better than another for whatever reasons they choose.
Again, this is obviously all just my opinion and clearly many are already excited about the contest which is great. I do hope I'm completely wrong about the game modes and am looking forward to seeing what everybody comes up with.
