I dont play a lot of Death matches so i cant say anything about most of them being crap or not ......I thought Saving Ryans privates was a Joke.....amusing the first time around ..after that it offered nothing
But the races i have run, Drift Kings is the only one i have ran and booked marked to run again .......most of the ones i have played are just fun for a few laughs but not much more
And that is exactly how they became so popular. Players played it once or twice, liked it and with enough likes were verified to be made public for all of us players.
R* fails to check the stages properly though before verifying them. They went on the whole "Oh players love this stage, check how many likes it has - let's verify it!". Of course they do not have the time to check each and everyone of them, they prefer the players do their work for them.
My gawd, I knew that there weren't many brains floating around in this game - the content creator just showed me that there are less than I initially thought.
And come to think about it, there aren't any R* created stages I'm tired of even though I sit and play deathmatches each day throughout the day.
You can see double standards of quality between players created and R* created.
