I'm may not be the target audience if this is recently post-college, but the thing that strikes me is these activities feel a bit performatively male.
I guess my hot-take is there are certain things that people genuinely love (e.g. improv, dnd, video games, rock-climbing) perception be damned, and there are certain things that people do because they are socially acceptable stereotypes for males: drink craft beer, whiskey, poker, grilling, sports? And that it's about 20x easier to make real friends from the former than the latter.
My experience has always been if somebody says "Come over for poker night," it's gonna be much more awkward than if somebody says "Come over because I'm gonna play video games on the couch and smoke a joint and it'd be fun to have somebody to chat with while I do that." [I'd be curious to hear where other people fall on that topic]
Anyways, not to discourage your current tack, nor even say you should do a blunts and video-games event, but I just think some of the activities on the website seem branded to a very narrow type of guy (business majors? for lack of a better stereotype)
