With Netflix you may rent dvd's but you get them in the mail and you send them back in the mail in a prepaid envelope. You pay a base price and check out dvd's for as long as you want. You may order more using the website.

What I want to do is find a website that I go to and I sign up for an account there and I choose a game to rent and they send it to me and when I'm done I send it back in the mail in a prepaid envelope.

Here is basically what some choices are...

Today is my first day of researching this. I will be renting games for Xbox 360, DS, and PS 2. What are your thoughts on what the top companies are? What random issues should I be concerned about? Thanks. :)
