Generally speaking, I wouldn't sell anything to fund new games. I tried that in the past by trading in older games I had but I got next to nothing for them. I'd rather spend another week or two saving the extra money and keeping what you have – but that's just me…
Fingers crossed, I should have a PS4 in another two months time if all remains well. I've set myself a deadline of the end of January. I'll admit that I'm becoming fed up of waiting now (and I think I've been very patient). If there's no sort of better deal or bundle going in the post-Christmas sales, which is what I'm hoping for, I'm just going to have to 'bite the bullet' and buy one. As I've said before, I've saved a £50 Amazon gift voucher from last Christmas which will ease some of the burden and I've already had a hint from a family member within the last week that I may have another voucher at Christmas (no idea of the value). They know only too well that I've been moaning on for a year now that I've been waiting to get a decent deal/bundle – preferably at or under the £300 mark.
I had an ageing Xbox 360 and a lot of games so traded them for a PS4 a couple of months ago, i had not seen a PS4 in action but on advice from my son i went for the PS4 instead of Xbox 1 as he said it had better graphics (he has PS3 so i thought he may be biased) having seen a few side by side videos i am glad he talked me into it, its a fantastic console, the only gripe i have is unlike Xbox you cannot (as far as i know) get a controller that you can use rechargeable batteries in, the battery life of the PS4 controller is a joke if you have the light on high and vibration turned on, i have had to buy a USB extension cable as i have the controller plugged in most of the time.
With regards to PS+, I'm still unsure what you can and can't do without having a subscription. There seems to be no clear guidelines or chart that I've found. I've never done any sort of online console gaming before so I have no idea what the situation is. As I generally avoid FPS titles and don't 'do' multiplayer, which seems to be the bulk of why you have a subscription, I don't really see the point in it for me to be honest. It would seem a waste of money if all there was other than that was a few 'free' games you could download. Even as someone who at best can only get gaming a couple of times a week, I don't see how I could get the value out of it. I really have no idea what to do about this at the moment. The jury's still out. Maybe get whatever the shortest subscription is available and trial it. I do want to give this whole 'on-line' scene a go to see what the fuss is all about, but I just haven't a clue what I have to do to go about it or what to expect. One of the reasons I've delayed in buying a PS4 for so long isn't so much because I feel priced out of the market still, but it seems a lot of it's functions/features are on-line. I just want to 'plug in and play' console - and spending all that money on garnish I'll probably hardly ever use has made me hold back so far.
I think the majority of gamers buy their games for the on-line play which gives the game longevity, i am the opposite to you in that most of my gaming is FPS, having said that my current favourite game which i haven't been on-line with is Assassins creed black flag, i also didn't go on-line with this game in the very short time i had it for my Xbox 360.
If you buy a bundle (i bought the Destiny bundle from Game store) you get 12 months PS+ free so can give on-line play a try.
The games you get free every month have caused more arguments in forums than any other subject i can remember, my view as someone who has always had to pay for on-line play (Xbox) is they are worth the money, this month we have had -
The Binding of Isaac: Rebirth
Steamworld Dig
Escape Plan
I am not to keen on the Binding of Isaac but the other two are fine, December will see us get our first AAA game which is Injustice: Gods Among Us Ultimate Edition (PS4) and we are also getting Secret Ponchos (PS4).
As i don't have any choice and have to have PS+ for on line play i think these games are a bonus, until quite recently we got nothing from our Xbox subscriptions.
