Love the game, but would like to know on some stats, how much the upgrades are worth. Seems like you get the same for a upgrade worth 15 or 50 as one costing 500.. (like the posters and hats.... And wallpaper and floors). Would be great to have to replace the posters, and know why. Same with hats, wallpapers and floors.. Do i get more from owning 3 of the same upgrades, or is one of everything enough?
