what would be the reason for anyone to port a HL2DM map over to SP?
Because not everybody enjoys playing MP games. A lot of my readers never play MP games, and with so many DM maps out there and so few SP maps this competition is hoping to make more higher quality SP maps available. Dedicated SP players play all sorts of maps, not just the bigger mods, the ones with stories etc.
how will it be played and for what purpose? - please give examples.
It will be played like any normal SP map. See the
HoloReality. It has a converted DM map and is the best one in the mod. The purpose is for enjoyment.
do the producer/s of said competition understand there is absolutely no joy not only in playing a map designed for MP in SP but also vise versa?
I beg to differ. The quality of conversion and choice of DM map is very important. Clearly not every DM is suitable for conversion but some are. The use of "Joy" is a subjective term and whilst you may not enjoy playing converted maps others may. The example above gave my lots of joy.
nowhere in your post nor on your sire does it explain the idea behind this project. only the "How". but..."Why"?
One problem with ths SP mapping community is most of the maps released are of low quality. The bigger and better mods take a long time to produce and release.
This competition is hoping to encourage mappers who wouldn't normally release SP maps to do just that. There are some great short, story-less SP maps available, but not many.
It is hoping to make available a large selection of maps that are at least equal to some of the maps released by the SP community.
And lastly, it is also hoping to draw a little more attention to SP mapping.
I suspect, and I admit I could be wrong, that you don't play many SP maps that get released, maybe the bigger mods but not the smaller ones. The problem for SP only players is the choice of maps available. Most of these don't have the technical quality that a lot of DM maps have. Whilst adding a few enemies and making small changes to the layout and design won't produce a masterpiece it may create something better than the drivel I have to constantly play.
Irrespective on your viewpoint of SP maps and players, from our point of view it's a potential goldmine of maps waiting to be played.
I mean no disrespect either but your reply is reminiscent of a pervailing negative attitude within the gaming community. I am not suggesting you have this attitude, you may just have a healthy secpticism, but instead of looking at the problems and negatives why not approach things with some optimisim. Just because you don't think it is worth it or like it, doesn't mean it won't work or it's a bad idea.
My thought process was simply:
What's the worst that could happen if I run this project and competition? People laugh at me and say it's a terrible idea. Okay that's no problem, I rarely worry what other people think of me. AND
what's the best that could happen? We get lots of entries and SP players have something good to play and a few mappers decide they will try their hand at making a proper SP map.
I have already admitted in other places that it *may* be a bad idea and may fail miseribly, but I have decided to stand up and put my own money up in the hope that it will work.
Everybody can find fault with ideas, the question is do you (You, as in the "community") want to always be negative or say, "okay, what can I do to make this better?".
