I hate this "exclusives" war everyone's waging, as if multiplats (which are non-existant on the Wii U) don't count.
I hate list wars so I won't stoop to that level, but only Bloodborne and TOLU on the PS4? Okay. I can also totally see all those Fable, Halo, Forza and Gears of War games getting ported to PC - oh wait, they're not, even the 360 ones weren't ported. Sorry, but the cost of investment versus the return is just better on the PS4/XBone, no matter how you slice it. One look at the upcoming games tells you everything you need to know.
I'm talking about exclusives because OP has a gaming PC, therefore multiplats are hugely irrelevant . If he didn't have a gaming rig, I would recommend a PS4 or XboxOne in a heartbeat over a Wii U. Hmm...Yes. Exclusives wise, TLOU and Bloodborne. At a push you can include stuff like Transistor/Velocity? which is hardly next gen.
Fair point on the 360 ports. I stand corrected but MS losing bioshock, alan wake,mass effect, and rumoured sunset overdrive really leaves me with little faith with XBOX exclusivity for anything interesting. I bought my XBOX 360 on the premise of how amazing those games looked.. and they were amazing... and they got superior versions on PC and were ported to PS4. Never again will I buy a MS console. Just compare MS exclusives last gen versus PS4 and Sony kills them (albeit most of Sony's good games coming 2-4 years into the console's lifespan).
Upcoming games wise, the PS4 will do well exclusives BUT whats the point buying one now? I'd rather get one 1-2 years down the line once the delayed games like KH3, FF15 and Uncharted drop and the console is cheaper. Right now the Wii U's exclusive library betters the PS4s which is what counts whens someone has a gaming rig. In the UK the Wii U is already very cheap so I doubt the price will plummet much further whilst the PS4's will in 1-2 years time with a possible slimmer iteration. For me, if you have a gaming PC... buying a console is about buying one when it has a healthy library of games which you can access easily at that moment in time. In that regard: Wii U > PS4 > Xbox1 IF you have a gaming PC. If you don't, then stuff like DA I, GTA 5 and Far Cry 4 would push it in the PS4's favour. However, since OP has a decent rig, the Wii U wins IMO [may require an upgrade to graphics card]. PS4 IMO is a no-brainer purchase in 2016 once KH3, FF15, Persona 5, and Uncharted have all dropped as they're experiences a PC can't offer.
Then again, I do appreciate your points. If Smash Bros, Mario Kart, 3D World, Wonderful 101, Donkey Kong, Bayonetta 1+2, Winder Waker HD and the upcoming Xenoblade game do not appeal to you, I would
NOT touch the Wii U. I personally clocked around 100 hours on MK8 (multiplayer) + Smash Bros alone, completed WW HD which was beautiful for around 30-40 hours in the first few months of having a Wii U so I'm happy with my purchase. HOWEVER, if those games don't appeal to someone from the outset, then the Wii U will only disappoint.
I think you're looking at the situation from which console is a better purchase. I agree, a PS4 is a better purchase. But when you take into account already having a gaming rig, things look very very different as GTA 5, Far Cry 4, Dragone Age inquisition and the upcoming Dark Souls 2 remake all become irrelevant.
