I`ve owned a few games through means of trade ins and other ways. Let me rank em for you from best to worst.
1. AC4, the most fun game on the Ps4 and very pretty
2. Outlast - The most interesting experience this system offers, a great survival horror where you can't fight but have to run and hide to win.
3. NBA2k14 - Best looking game and a solid sports title
4. Need for Speed Rivals - Very fun racing game with impressive visuals
5. KZ SF - Run of the mill shooter with great visuals
6. Battlefield 4 - A technically good shooter, nothing great, thought the campaign was meh and wasnt into the MP, but I don't like MP shooters
7. Resogun - Fun arcade ship shooter, just didn't hook me at all
8. Contrast - Puzzle game, ok for free, not worth any money.
9. Madden 25 - A joke of an "upgrade". Not worth a rental
