What the fuck OP. I know you're talking about PC games in general, but this is the RPGcodex and if 2015 is looking like a bad year to you, you should find a new hobby since this is shaping to be one of the best years of all time for RPGs, rivaling years like 92 and 99. It's never going to get this good again, it's a miracle that the 2015 release list looks as good as it does after a 10-13 year dry spell.
If Grimoire gets released, Torment delivers and Underworld Ascendant&Seven Dragon Saga were both released during 2015, I don't think that even any year in the 80s/90s could compete with 2015(*), espescially if you also count the JRPGs. Almost all subgenres would be covered in some form, some by games that might end up being some of the best games in their respective subgenres: Grimoire (TB blobber), Torment (storyfag), Pillars of Eternity&Serpent (RTwP), Seven Dragon Saga (tactical RPG), Underworld (FPP 3D dungeon crawler), a ton of TB CRPGs (AoD, Underrail, Shadowrun etc), Witcher 3 (AAA storyfag/insipid hack n slash) [SMTxFE (+Yasumi Matsuno's new game)=SRPG, Bloodborne=ARPG, Persona 5 (and Xenoblade X if it doesn't suck)=JRPG]... only thing that's missing is a FPS-RPG, a really open sandbox RPG and/or a Realms of Arkania/Darklands type game.
(*) There were more releases back then, but there are more potential 4/5 star games in the 2015/2016 line up than there were in any individual year during the 80s/90s
Or each and every one of those games might end up being like Wasteland 2 (ie a dissapointment), but hey, 2015 would still be better than any year between 2005 and 2013. That's how much things have improved in a couple of years. Dragon Age Origins was codex GOTY in 2009, now Wasteland 2 is kind of meh because there's so many other TB CRPGs in the horizon/on the backlog. You should be sent back to the year 2008/2009/2010 so you would learn some gratitude.
