I played MH3U online 1 month before 4U release, and the general community sure is great. People usually stays even after their urgent done and payback the deed. Though honestly I can't understand why people not doing everyone's urgent, especially when the urgent is a elder dragons. It's easy money as I sit a top 1kk zenny from selling Akantor, Ukanlos, and Dalamadur materials.I get the feeling everyone is in a rush to get to the top of G-rank. When I jumped in 3U something like a year after it released I only encountered a handful of people like that over ~100 hours. Everyone was very chill and would take turns posting quests. If someone randomly asked the best way to get X material a lot of people would just offer to help farm it on the spot. It was the best online community I've ever seen in terms of generosity and helpfulness. The more restricted communication and likely higher concentration of kids on 3DS might contribute too.
