I think 1 week is too short
Actually thats the thing that makes this work, by setting a short deadline (and some restrictions) you force people to make mods aimed at '1 subject', rather then them trying to trow in as much gta natives as possible, making a multimod with 120 features, just like all others...
I would participate in the contests, but we would need to think of fun contests tho, not just 'make a weapon mod'/'make a vehicle mod', there need to be a few rules, and the contest in general should result in fun mods for the community, some ideas:
The oddest job: Create the most fun odd job (side mission) you can think off.
The coolest superpower: make a mod that gives the player some kind of powers known from any (referable) comics character. (something better then superstrong punch/kick/trow)
The most unique vehicle: Make/mod a vehicle never before seen in the gta iv universe, while it should still be able to take you to places, a stretch with 12 wheels and a bathtub, a police bike, a submarine, you name it! (restriction could be having to use a iv vehicle as base)
The best g4m crib: Here the aim would be to make the nicest model replacement that adds a gta4mods house/office interior. (limited too a specific model so every1 has the same amount of space to work with)
The prettiest world tweak:Make a modification where weather, water and textures (no model changes) look different. (can be related to subject, like; make your interpretation of GTA IV:Vice City, possibly restricted to a small area since theres only 1 week)
I would also add something like 'The scariest horror movie' but most machinima's take alot longer to be put together afaik.
Oh and as u can probably tell, the above include: scripting, tweaking, modeling, texturing
Now we just need moar ideas like these
