Not your fault in my opinion . Not the players fault either . In every gaming group , there will be differences . if not , it will probably be pretty dull everyone thinking the same . In any part of life , in any tipe of social interaction , there is always a chance that for no good reason people will not like whats going on . In an RPG group is the same . and its fine . In the best case scenario , you will be able to openly talk with the group , get a better grip and adapt . But best case scenarios are hard to come by . Not everyone actually knows what they want , or has the social skills to listen to opinions and provide theirs without friction . Not always you will be able to create a combination of whatever your players want . And not always that combination will be to your personal liking Keep in mind . Some times , groups are not meant to be . Do try to solve it . Do your best , and it will probably resolve . And if not , at least you know you tried the hardest
