True, but many people are struggling with the recoil still.
Because gungame has much better weapon progression and maps, and it always had newer maps and casual and competitive players enjoyed it a lot. Valve basically dumbed down the gamemode in order to make it more palatable to players, and when it turned out to be boring to newer players they just never wanted to play more.
My opinion is Valve should not try to add community game modes to the main menu, because it creates a false impression. Just ask yourself, can you say that Valve can support Surfing servers? How many maps will they support? 10? 20? 30? Can the Surf mode be summed up in 30 maps?
Also, Surfing in CSGO is very dependent on tickrate, so we don't know how it would feel on Source2 either.
There were some reports about Surf being a new official gametype like Arms Race and Flying Scoutsman but I really would like Valve to not mess up Surf like how they messed up GunGame and ScoutzKnivez.
An excellent video, it is extremely well made and edited.
