i'd love to see a lot of old levels i've seen in 2009 to be in here, like that one 'live life as a trucker v.02' or something with all the roads, the trucks, the motel, or you could be a cop. the original version of the 'robloxian international airport', that one highway level with the different areas where you could choose from a few cars or the ghostbusters car, and a lot more
or pretty much a majority of different levels you see on the early jj5x5 videos
though i'm going to wait a little and see if RBLXDev actually takes off and becomes open
