I just found out I can access OnLive However, I got a 130 Mbit/s down and up connection, so that might explain why I can access it without issues, and other people can't. It's cool nontheless, I've been able to play a lot of trials and demo's.
OnLive is the main competitor of Steam. It works radically different. With both systems, you buy a game online, which is then linked to your account. But instead of storing files on your computer and you playing it from your computer like in Steam and regular DVD's, the game is started on a server somewhere, and everything is streamed to you. This means that you only need a shitty netbook to play a game like Duke Nukem Forever on full settings. The only thing that matters for quality is your internet connection. Lower ping = higher resolution obviously. You should try it, I found it great for quickly playing a trial version of a game.
@Alsnana: Show some intelligence and ask a question instead of saying "Wat.png". It's really annoying. This is the second time I see you doing it. >.>
