and by all means, all you need is good internet, and maybe the $100 Onlive Console ONLY if you have a PC that is so low spec it cannot run it, ALSO if you have an Icecream sandwich or higher phone you can online on it to (lol android has a sweet tooth)
$10 a month to play a fairly big library of games any time you want is pretty sweet.
I myself, love the Trails, but only as effective demos. I prefer to play my games physically, Onlive is great but is feels like (which it really is) just an Interactive Video stream with all of it's off gamma and particles glory, I'm sure its just my Laptop though.
