Seriously, BF4's campaign was boring trash. I got through most of the game before it deleted my save and I said fuck that. They should just put all their effort into the multiplayer which also launched as a steaming pile of shit. Then maybe, JUST maybe, it won't launch as a steaming pile of shit.
Not for one game, no. Maybe wait for a price drop? Quantum Break and another Halo are supposed to be coming to X1 this year. Also Project Spark. That's all I know that's been confirmed for this year. If you're interested in those 3 games, anything that's already out AND have the money to burn, go for it. If you want an X1 just for Titanfall and have no interest in the above games, then no.
I saw the recent Binding of Patrick yesterday and I got excited for this game to come to PS4. Wasn't interested before but I'm glad I watched it. Also glad it'll be free for PS+ members when it comes out.
I don't really base my purchases off of reviews unless it's something I'm iffy about like Thief (Which I'm waiting on for a price drop). That said, whenever I do look at a review, it'll be from GameInformer or Giantbomb. Most other sites reviews are shit. Looking at you Polygon.
By the way, I think you should've made it more clear that your complaint is based on early multiplayer game reviews. Doesn't seem like some people get it.
Also, I rarely buy games day 1 unless it's something I really look forward to (which is mainly single player games) and indie games. So reviews are pretty useless to me either way. Besides a bunch of indie games I've bought since January on PSN, the only retail/AAA game I have bought/pre-ordered is Infamous Second Son, but only because I wanted the collectors edition. If that wasn't a thing, I would've bought it digitally the day it came out if it isn't buggy as hell (Which I highly doubt because Sucker Punch is great at polishing their games). Multiplayer games like Destiny, I will be waiting on to make sure it doesn't pull a Battlefield 4. Games that I'm interested in like Dying Light, I will have to wait for reviews because as cool as Dead Island was, it was broken as hell when it launched (Good thing I never bought it).
