You may already know this, but because a lot of my posts have been on Final Fantasy, I thought some of you may be interested.
The annual Final Fantasy sale is on PSN (!!) and includes some of the originals (Final Fantasy I and II), the classics (VI, VII and VIII, which I desperately need to play) and also some of the more modern titles, such as A Realm Reborn, Dissidia (prologus is a steal for a little less than $2) and XIII-2 (which I think is a good game even if you hated XIII) for those getting ready for Lightning Returns.
Most games are selling for about $6.50 (price will vary on currency - for Australians, this is the case) and they're usually $14.50ish (AUD) so you're getting over 50% off. If you've ever wanted to play these games, don't wait another 365 days, so get on it, kupo! The sale ends midnight on 6th February 2014.
