I went to town for the first time in a while, and before I took the trip I immediately checked the CeX website to see if there's anything of interest. Normally this doesn't provide much as my local branch is pretty weak on the selection, and to my surprise they had one game in particular that caught my attention. I did check eBay to see what the prices were like before I would try and hunt it down.
Upon going into the store, they didn't have it on their PS3 selection or on their glass shelves so I asked the staff if they had a copy available (just in case, since sometimes people can beat you to the punch). And miraculously they did as it was behind their counter. I was allowed to check the condition and I went for it, especially considering I did have CeX vouchers already so I only paid for half of what it was going for.
So yes, I now own Fist of the North Star: Ken's Rage 2, the 2012 Dynasty Warriors spin-off game by Koei Tecmo for the PlayStation 3. This is one of the most expensive localised games out there and that's partly due to how it was not only released at the end of the PS3's life-cycle, but North America did not receive a physical version outside of the Xbox 360 release, and considering PS3 games are region free (99% of them that is) it's no-brainer that importers would try to grab the UK/EU versions.
Looking at CeX's pricey PS3 games, there's a fair amount of other expensive ones that I don't own like Godzilla (which had a PS4 version anyway), Blades of Time (a Konami game), the HD remaster for the first Killzone game (which again, will likely get a PS4/PS5 re-release via the PS Plus Classics programme), and Lost Dimension (published by NIS America which I reckon will get a re-release also).
