We tried a "fun" virtual office tool around covid times called Gather Town, which is 2D. People liked the virtual office, but only for certain company events like hackathons or meetups. The general audience totally prefers something like slack for texting and meeting.

We also had an issue with a few people getting motion sickness from any 3D games, so any 3D virtual meeting space was out of the question for our company. A flat 2D UI would be preferable to the "low performance" option that this project provides, which is quite jarring.
