The problems I have with Roblox is the fact that they announce some pretty cool updates on paper, but in reality when you try it yourself is very unoptimized, glitchy and complicated to work with and never get to look good like how they promote it, the prices for their Builders Club upgrades are very overpriced at the point that is unnecessary, also there are a lot of questionable design choises, the big majority of levels created by players are cringe worthy, and the community is, well, it's the Roblox community, you know how it is.
