People who are still on the fence about certain games, there is a good chance your local library has a videogame section. Mine has a vast PS3/360 section with about a hundred games each, and very good games as well, been playing through Dark Souls I got from my library. They also have a growing PS4/X1 section thats no joke either, and I dont live in a particularly "rich" area.
So yeah not a lot else to say. Go check out your local library, they probably have games you can rent for free. Best way would be just google your library and use their media search to see if they have them.
