in like 2012 i used to play somesort of call of duty in roblox game no idea what the name was but i remember they suddenly changed all weapons and made some cost real money so i stopped playing
I played that same (or very similar) game sion, don't remember the name but it was also around 2011-2012.
Dark and depressing obby (sorry for the advertising)
I haven't played roblox in years, but i remember enjoying a variety of different games. I have especially fond memories of natural disaster survival, murder mystery 2, and survive the disasters.
Actual good tycoon games are overlooked, I've always enjoyed Theme Park Tycoon 2, Retail Tycoon and Restaurant Tycoon
I can't pick one but I have three, those three being: Black magic 2, Bad business, and That one sonic unleashed ROBLOX fan game.
