This is what I say. I am writing this on my PSP and I really want Jagex to make a version that runs on Javascript so I can play on my PSP. They could lower the maximum number of players in a world so it won't lag. If you go on youtube you can find a few videos of people playing RS on PSP's but I don't know how they do it. If anyone knows about this, or has some constructive criticism, please post.
