I'm considering getting the Mass Effect Trilogy by downloading it from PSN since I cannot find the game from any other game shops. Right now it's for £25 on a sale, brought down from about £40-50. I'm just wondering if it is worth. I'm kind've bothered that if I do not like it, i'll want to refund and i'm not sure if PSN do refunds. Are there any other problems that arise when downloading from PSN? If so what are they?
