I was sorely tempted to get the PS4 Killzone/365 PSN offer but what puts me off is:
a) lack of release day games that actually appeal
b) Killzone is okay but it's not GTA V
c) there will be bugs and lots of problems
d) at the moment I don't feel I really need it!
e) cost of games is very high right now (£50)
BF4 seems to be running much smoother now and I've put in a good 25 hours or so since I started playing this week so I don't think I'm in desperate need of a new graphics card as I had initially feared.
So, my non-existent funds are safe for now. Mind you there's a few things I wouldn't mind for my PC: new SSD, GFX card but most of all a NAS perhaps with 4 (2TB) hard drives for RAID 10. Ooh baby. Yeah.
