BONELAB

The game itself is really not worth $40 (crappy story mode that the rest of the game is locked behind, easy to exploit dev tools, undisclosed use of AI for posters and such) but if you get this on PC and download Fusion it's 100% worth it for the multiplayer physics and avatar capabilities. Most of what this game does with its story is done better by its predecessor Boneworks, so if you watched the trailer for this and thought it looked cool definitely consider buying Boneworks instead. If you are looking for VRChat with fewer NSFW avatars (to my knowledge since most of the mod.io ones are moderated) and with physics that add a whole other layer of fun to the game, buy Bonelab for Steam and download Fusion. Do be warned, though, Fusion is very resources intensive due to it requiring constant downloading of mods to function properly and calculation of physics for multiple people at the same time, so if you do get Fusion make sure your PC is at least decently powerful, not a laptop or something.
