I don't know how I review what's basically a game engine, so I'll just list off a few of my favorite games on the platform

-Prison Life
-Natural Disaster Survival
-The Prison Life clone that was always #1 on front page when I played, didn't have the same charm but there were more features in it
-Frappe (Frappe doesn't like me very much)
-FREEROBUXGENERATOR which was on the front page for like a day, I miss that game. the real humans playing the game with me were very nice

I'm unaware of what Roblox is up to these days but I had fond memories of playing it a few years ago
