Split screen would be pretty important. I guess that only counts if you're going to have more than just PC games though.

Some kind of "stats tracker" feature would be cool. Such as, how many games played/beaten. How many hours you logged for each game, even total.

Maybe the ability to play in a windowed mode. I say this because generally when I'm playing games on my PC, I chat with friends as well in a separate window.

Maybe the ability to watch your friend play in a "picture in picture" window.

A big concern I've been hearing from my friends is about games we already own. Are we going to have to re-buy them to play them on Onlive? Now I understand, if we already own them, we can just play them without having to use Onlive, but lets say that we want to play it on Max settings, or just have a universal place where all of our games are stored. That's a BIG deal with quite a few of my friends. And I don't really blame them. I have at LEAST 6 games on my Steam account and a few more off of them.

Also, are you able to access your account from multiple computers? Or are you stuck with just one computer? I personally have a desktop and a laptop, and it would be nice to be able to jump on my laptop on break at school and game away.

In game messaging? Chat? Sending pictures/videos and the like.

Achievement system?

Hope that's enough wishlists for you.

Don't get me wrong, I'm really interested and have even signed up for the beta, so here's to hoping it comes out well.

well i think ability to leave system as it is the most important of them all. every few months i finda 2 kool game tha tsays i can't play it because my 3d card is " obselsete"

and to tell u the truth, i am fed up of this " obselete" now.

Features i want

1. Cool display
2. interface for chatting
3. pause button
4. online radio

Hmmm things that I would want in onlive are messaging, splitscreen, good display, and pause button. There are a few other things I would like but that pretty much sums it up.

I'd like to see an easy means of recording things. Some gamers like me, the ones that pull off crazy challenges and such, love being able to put our achievements on YT for everyone to see

A good messaging system with built in Ventrilo or something similar. I pretty much agree with all your points, and perhaps OnLive can have a built in scanning system that will read your disc and then unlock access to said game. The idea of a picture window sounds terrific, I would love to see that feature as well.
