It's nice to read someones thoughts on this written out. Whenever someone is speculating on the future of tower I've seen multiple people start to compare it to VRChat's success. I don't think the two should be compared for two reasons: Custom Player Models and Gameplay.
Custom Player Models
Before VRChat blew up I'd see a lot of .webms pop up on sites of Hank hill and Agumon hanging out at a tavern, and people were always asking what game they were looking at. Being able to pick from a massive catalog of recognizable characters leads to hilarious scenarios you thought you'd never see in a game. This leads to youtubers and streamers coming in getting views because they're petting anime girls as Peter Griffon while a Darth Vader dances in the background. These youtubers capturing "random" humor with recognizable franchise mascots starts blowing up, which of course snowballs into popular memes. The dreaded "Ugandan Knuckles" was a massive boost to the games popularity, and I hear people who don't even play many videogames saying his stupid catchphrase. If you like this meme that's fine, it was kinda funny just done to death.
This is where I think one of Tower's greatest weaknesses comes in: the horrible player models. No offense, its early access and they are just place holders and I get it. But if you don't feel like being a whacky skeleton or a bopping milk box, your only option is a Disney club preteen.
Where VRchat is garnering all its interest, Tower is probably scaring away potential customers at the moment. You have three options to represent yourself, and two of them are basically gag models. I was so pumped when they were working on the knight model and I just remembered its gone.
I think Workshop Player models will be one of the updates that brings a bigger batch of new players because aside from the novelty of well captured arm and hand gestures, It'll now have the primary ingredient of VRChat's popularity. We'll be able to accurately represent ourselves in our virtual space, as well as create interesting scenarios with recognizable characters.
This is where you're really comparing apples to oranges. Gameplay is something that Tower Unite is jam packed full of, and VRChat is barren of. Not saying that as a reason Tower is better, but as a reason why you shouldn't compare the two.
Tower offers variety in gameplay so it can scratch a wide assortment of itches, whether its just golf and bowling or intense FPS. We're only at roughly half game worlds playable and no arcade yet, but there is fantastic variety already. If all these games were built around VR controls, they'd be very different and much more enduring to play.
Meanwhile VRchat offers the opposite. The main draw to gameplay is the well captured body controls. This doesn't really fuel gameplay scenarios, but it fuels social interactions greatly. There are fewer activities with no sort of progression or reward systems in place (as far as I know correct me if I'm wrong). VRchat focuses almost exclusively on the social aspect, and I honestly think its more of a chat program than it is a videogame. MSN Messanger had bowling AND Uno. Not a jab though, Its core goal is creating virtual social environments and they have excelled. They never promised a variety of games to play, that's something Tower promises and excels at already.
Sorry for the wall of text.
VRChat's popularity is almost completely owed to custom player models leading to youtube popularity and memes. This is something Tower will be capable of in the future but currently is not. Tower encourages a social environment but also puts a huge emphasis on gameplay variety, something VRchat does not. Throw in the VR factor and you're comparing apples to oranges.
(Also I am still salty about the knight player model getting scrapped.)
