Roblox is basically comparable to a Unity + Steam Workshop hybrid, and the ratio to good games to bad is probably a shining gem in a seven foot pile of coal. I have played some really, really good games that were very fun that I still can't get tired of, but the gameplay is ruined by 6-10 year old children who think they're cool and tough for being on the internet. Plus the 'XD' face is on par a religious gesture.
