Runescape is by far the best MMORPG out there. It takes the longest to level and has such massive content that I have been playing nearly 5 years almost every day and have not maxed out my lvl yet or done even half the quests. It takes a lot of thought and there is a lot of risk to it (losing expensive stuff if you make mistakes, etc.) -- which makes it pretty adrenaline-charged for an MMORPG. Takes a lot of planning and thought to do it well, because many of the skills build on each other if you do them right. Runescape was supposed to be for ages over 13, but a lot of younger kids play because it has a limited free game on some of the servers. Most of the serious players I have played with are adults though. It is really not a kids game. It is way harder than WOW.
If Stellar Dawn is half the game Runescape is, it will be a hit! I cant wait!
