Seems like a lot of folks are not really interested in the quirky sport, so saying fans are rejoicing because of this announcement sounds like they don't really understand why people played HL.
Its like saying Dark Souls fans rejoice because From Software announced a fitness spinoff called Yoga with Solaire. Okay actually, they might. Bad example.
I went to ddg looking for yoga with solaire and then found nothing and was heartbroken.
but yeah I'm a huge HL and HP fan in general and I'm planning to skip this one because I don't really care about quidditch. its only real interest to me was as a cool plot tool. nothing more.
Honestly they could've had a quidditch minigame in HL. The two that are in it are fun, but they either need to be replayable without having to start a whole new story, or add more minigames based around causing mischief and having fun with your wizard friends.
I could see a quidditch game kinda work if it was like a hero shooter or whatever. Each team has a roster of certain characters with different stats to fulfill the different roles. There could be a snitch, but just make it so incredibly fast that it comes down to pure luck if you happen to catch it. Or just make different playable modes like "no snitch" and "with snitch".
That's quite besides my point but I'll answer in two ways:
Firstly what defines "working" isn't really your choice. If the goal is to have fun the silliest stuff can be called "working". If the goal is to escape reality for a bit then pretending to be a mermaid might be quite effective.
Secondly, my point was just that there is a game, played by people that are probably enjoying themselves,, which could probably be translated into a Video game. Just like any other sports.
