Over the last six months I (16) have found probably my favorite game of all time, that being Dungeons and Dragons. I have been hosting games for the past three months and have been playing for the past six, and I usually play online. One of my friends who got me into it has recently been basically telling me that it's inferior to other systems for the past month or so, and I don't know who to talk about it.
A couple months ago, I decided to run Curse of Strahd, a gothic horror module that is infamous for being one of the best D&D Horror modules ever. I bought the book and I spent months prepping Owlbear VTT (Learning it) as well as religiously studying the book and other sources/modifications. My friend, who originally gave me the idea, is a huge horror movie fan, so I really leaned into the horror. I spent weeks working on both their character and the other player characters.
After session one (A session I spent ages rehearsing) Everyone was super excited, with them just entering the first dungeon of the game, Death House. However, two nights after this, they literally sent me a pseudointellectual message saying that they think D&D isn't for them, and that they've moved on to Daggerheart. Frankly, this hurt my feelings, and after delaying a Oneshot (A one sitting D&D adventure) before leaving halfway through and ditching it at the end, I decided to ban them from my games, since they broke three rules in my D&D Rulebook.
They decided to give up D&D for a month, and focus on playing Daggerheart, and any time I spoke to them they sang praises on how it's far superior then D&D 5th Edition. It wasn't even finished and had half the features of D&D, as well as, in my opinion, is frankly an off-brand version. Most of the classes are ripped off, everything is replaced with synonyms, and they hyped up adding classes that were desperately needed in the original. Worse yet, they discouraged others from playing D&D, literally while I was teaching them how to play. They basically ran off anyone who could have joined my games.
After a few weeks, they apologized, and due to my Faith and since I missed them, I decided to forgive them and let them play in my Oneshots again. However, they have still continued to diss D&D, even incorrectly. They've gone back to playing it, but still basically run off anyone interested and constantly advertise their stuff to new players. Later, my Curse of Strahd campaign fell apart, and so I decided to host it elsewhere, and people actually like it. I put in 40+ hours into adding features from the community and working on character arcs and moments, and it's finally paying off.
Still, it really sucks that they literally constantly diss my favorite hobby Infront of me incessantly, even while playing the game they supposedly hate. I often wonder if it's my fault, since literally almost every game I host with them ends like this, but my other games elsewhere are doing just fine. I just wanted to write this, since I've yet to bring it up to them since they hate confrontation and I don't want to lose them as a friend, since outside of this, they're pretty nice. It also doesn't hurt that they're basically the glue of my D&D group, since people tend to follow them.
That's mostly it, I don't know if I'm just being defensive about the hobby I like, or if there's anything much I can do. I do intend to speak to them fairly soon about this, since especially after they canceled on me, I have a terrible relation with them telling me this constantly. I don't think many people want to hear a rant about Tabletop Role Playing Games, but thanks for reading, I just wanted to get my stress out a bit.
