Ok so before I lay my poor wii u to rest and put it in the archive, I suppose I better get every bit of gaming out of it that I can.  So I'm going down the list.  I'm posting because I thought others might find it helpful, especially since the Wii U will soon be on deep discount.  
Here are the games I own or have played and a short impression of each:
Assassin's Creed III - One of my favorites and I'm surprised others don't like it.  The PS3 version looks better, but it has loading issues.
Assassin's Creed IV - Get the XB1/PS4 version as the graphics are better, but it's still a fine game.
Arkham Origins - The black sheep of the Batman games.  It's pretty good, but not nearly as fun as City or Knight.
Ducktales Remastered - Purists might not like the new additions, but I think way forward did a great job.  Highly recommended.
Nintendoland - The only mini game title on the system.  It has way more depth than wii sports/play/ect but it is still just a minigame collection.  A couple are alarmingly fun.
Pikmin 3 - This starts off a bit slow, but once you get into it the game is quite fun.  One of the few games that makes great use of the touchscreen.
Super Mario/Luigi Bros. U - The Mario disc is just more of the same from the "new" series... nothing to write home about.  The Luigi disc is annoyingly challenging.
Super Mario 3d World - A fantastic game... reminds me of smb 2.  The only problem is it's really short.
ZombiU - I'll be honest... I'm not into fps games anymore and I never got around to playing this one seriously.  Honestly it feels like an ugly Left4Dead
DKC:TF - Eh, it's a sequel to the Wii DKC game.  If you want a 2d platformer that isn't as good as the New SMB franchise, knock yourself out.
Mario Kart 8 -  Second best game on the system.  Probably the best Mario Kart ever.  If you don't have a switch then try it.
Hyrule Warriors - Eh, it's ok if you like the Dynasty Warriors franchise.  I don't, so I quit about halfway through the story mode.
Smash Bros - I convinced myself to buy this one and immediately regret it.  Hey if smash is your thing it's a good version, otherwise it's just more smash.
Bayonetta (2) - I got to the last boss on the first one and the difficulty made the game tedious, so I quit playing.  It was fun up until then though and I'll probably finish part 2 eventually.
Ninja Gaiden 3 - Do you like Bayonetta?  Well it's that with ninjas instead of witches and demons instead of angels.
Super Mario Maker- Probably the 3rd best game on the system. Do you like Mario?  Wanna make your own levels?  Want access to infinite fan-created levels?  It's a no-brainer.
LOZ:BOTW - So they've sold more switch versions of this game than there are switches... yes it's that good.  Easily the best game on the system.  Prepare to lose a month of your life.
Shantae: Pirate's curse - a damn fine platformer.  It's short, but sweet.
Shovel Knight - see shantae
Just Dance - they all suck
Captain Toad - A very fun puzzle game with a cute story and a second quest.  Be warned... it's quite short for a full retial game
Mighty No. 9 - excessive load times, even after death make this game unplayable.
So for now that's it.  I intend to play Yoshi's wolly world, Wonderful 101, Splatoon, and the two Star Fox games.  After that I think it's time to retire it.  If there are any suggestions I'm willing to try them though.
