I use BT Games to exchange games. I get some really good deals there. Renting isn't something I would think of doing.... I guess I prefer having my own copies.
I plan on doing the BT Games rental thing next year when I move close to a BT Games Far better deal in my opinion...single player games don't hold much value for me.
I think i would rent if i knew the game would only take like 5 days to clock and another week to 'complete'. R99 is ok for a month but after that I think it becomes to much money for something you have to give back
I would not rent..I just wait for reviews and hear feedback from others.If the game is worth it and replayability is high then I make my purchase.Mostlty RPG's are a purchase for me.Adventure,racing,action games I buy second hand and sell them again after I completed them.
