How come WKC is 5 star and WKC2 4 stars platinum?

Both take the same amount of time to plat.

Great work as always though.

Both are rated as an 8/10 in the Platinum Difficulty threads on PS3Trophies.org, which would make them both a 4 star right now. However, given the amount of time that is needed to plat both games, I feel that they should both be 5 stars. WKC1 took me 513 hours to plat, which was all gameplay where I was there (no AFK gameplay at all), and I hear WKC2 takes around the same. Also, WKC2 has that one tough boss battle that is a trophy and the overall game might be considered more challenging than the first.

The issue is that ratings on ps3trophies.org varie over time and they have different ways to rate games.

The page of a game will give a game difficulty rating based on the average vote( or mean in mathematical terms).

Then they have another page that ranks games based on median values :

http://www.ps3trophies.org/forum/games/93140-collected-trophy-difficulty-ratings.html

I'm not sure which is best.

Ideally I would tend to say median value as the final number is less skewed if one lone dude votes a game 1 or 10.

 

The other issue is that it seems that after a while they stop updating the difficulty rating in the poll .

One example :

Dungeon defenders is rated at 8.4 difficulty.

But if you do the maths the average vote is actually 7.95, I can't explain the difference except maybe more people voted after they computed the average or in their formula they do some weird stuff like removing the top and worse vote...( would only give 8.05 so it isn't that).

And while the average is 7.95, the median is actually 9.0. ( the thread I listed lists the average at 8.03 instead of my 7.95 but it was last updated on 1/20 so most likely another person voted in between).

 

So anyway my point is that maybe it woudn't be a bad idea to move from using the average ratings to use the mean ratings instead ( especially as most games difficulty threads always have a few trolls that vote the game totally differently from everyone else).

PS : NGS2 is the highest rated game with a median of 10 and a mean of 9.31
