For those who do not know, RuneScape Classic is the name we now use to refer to the very first version of RuneScape, the original basis for RuneScape as it is today. As discussed in the RuneTek 5 blog, RuneScape Classic was RuneTek 2. When we upgraded the game engine to RuneTek 3, we renamed the first game to RuneScape Classic, and the RT3 engine took over the RuneScape moniker.
