Right now I'm building a huge, fun, plenty to do RPG game on Roblox. It will have skill levels (mining, lumbering, fishing, strength, crafting), these increase the more you practise them, the cap to them will be 10. You can increase the cap by buying VIP.
The game will also have classes, shop, blacksmith, tavern, castle, houses (like a tycoon you can upgrade your property), and a couple more buildings.
This game will go front page and I'ma give UCR some money.
