The official PlayStation Blog has published a list of games that are going on sale for under $20 between 28 April and 13 May. After going through the list here are some of the titles I believe to be worth a look.
I considered price and the Metacritic review score along with personal preference when compiling this list so keep in mind this isn’t the entire list;
This list contains the games that are under $25 and have a score of at least 75 on metacritic. For the two games included in this list with a Metacritic score under 75 (Far Cry 3 & Star Wars Battlefront II) are both titles I’ve experienced and enjoyed immensely.
The best values I see are the games under $10. For $15 you can play Darksiders, Injustic 2 and Sleeping Dogs. 3 titles for that price is great.
