Roblox has some cool games actually, specifically the ones that aren't "Generic stuff Tycoon #190214094" or "WHO KILLED RANDOM CHARACTGER#50923509??!?!?!?!"
I'd say the only games actually worth playing at that stuffhole are Armored Patrol, Galleons, someleft4deadgame, and Life on Planet Earth when stuffblox (the staff) released boatloads of updates and broke it over and over.
If this desktop didn't suck, I would go to Roblox and check my favorites list to remember that Left 4 Dead game and another game I forgot.
